Another one of Kakashi's anti-teamwork lessons is his regular lateness to team meetings.

Oddly, generally the fanbase glorifies Kakashi's lateness, since fans bizarrely find it endearing that Kakashi intentionally makes his team wait on him for hours because it's "honoring" Obito.

I don't think that Kakashi's lateness is at all sweet, touching, or whatever positive things fans associate with Kakashi's lateness. Kakashi recurrent lateness hacks me off. Being late to meetings may seem harmless and innocuous, since some of us just can't always arrive on time. But in Team 7's case, Kakashi's perpetual lateness is very rude and disrespectful, since Kakashi was late on purpose. And Kakashi was not just a little late; Kakashi was always a lot late. It wasn't just that Kakashi kept running into inconveniences that couldn't be avoided (which is what happened to Obito); he was late on purpose.

This bad habit might not seem like a big deal to those who know Kakashi's backstory and that his lateness is in "honor" of his deceased friend, but Team 7 doesn't know any of that.

Lateness means indifference, it means you don't care about the event you are attending because it's so trivial to you that you can't be bothered to show up on time, it means that something else is more important and more worth your time. If you are late to something, then you are attending because you have to and you're not going because you want to or because you're invested or because you care. Lateness means you're dragging your feet because you're avoiding your prior engagement.

If you are truly invested in something, you won't want to miss a minute of it. Especially if it's a group meeting, you won't want to keep people waiting on you, you won't want to disrupt things or stall things by being late, you don't want to miss anything with the group. You'll be there on time, or early, because you are so excited for an opportunity that you don't want to miss a second, or at least you don't want to miss much of it. If you care, you'd be on time or early, and if you don't care, then that's why you're late. Arriving to engagements early indicates eagerness and excitement, and arriving to engagements late indicates indifference and disinterest.

Kakashi isn't showing up for Team 7 because he wants to be around them, he's showing up extremely late because he has to be around them, because he is literally paid to be around them. Hanging around his teammates is so unappealing to him that he meanders to work every day and purposefully is very, very late.

For the record, I'm not harping on people who are late sometimes to events that they do care about. Life gets busy, I get it, scheduling conflicts happen, and I'm using this as the general example of what being late generally means when people are consistently late. Being late once is just an accident that couldn't be avoided; being consistently late means apathy and that you aren't willing to go to the trouble of altering your schedule or changing whatever is needed to make sure that you are able to be somewhere on time. In Kakashi's case, the lateness isn't an accident, it's purposeful.

Thus the message that Kakashi is signaling to Naruto, Sakura, and Sasuke is that: "I don't care about you, about this team, about any of it. My time is more valuable and more special than yours, which is why I make you wait hours every day while I'm goofing off, shirking responsibility, and wasting your time that you could spend doing other thing." And so the lesson Kakashi is teaching Team 7 is that "you shouldn't care about the team, because I sure don't".

If I were Team 7, I would start to assume that Kakashi must hate me and the team to always be so late because apparently hanging around me is just so awful that he can't even be bothered to do his job. And let me emphasize: Kakashi is receiving a salary to train these kids; he's not doing it as charity work. So not only is Kakashi sending an anti-friendship message to his team, he's essentially stealing money from the village by avoiding his salaried job.

It's incredibly selfish and self-absorbed of Kakashi to be so inconsiderate of his team, since every day he wastes copious amounts of their time by making them spend hours waiting on him, which is time that they could be using to improve their skills or accomplish plenty of other tasks or hobbies. I detest people who inconsiderately take advantage of people like this who don't show any basic consideration whatsoever for others and how valuable their time is. If Kakashi were recurrently helping people he just happened to run into like how Obito did, I could forgive the slight against his students, but staring blankly at a memorial stone is doing no one any good. 

Kakashi let these kids sit around for hours at times, waiting on him, because apparently the world revolves around Kakashi and everyone has to accommodate Kakashi's self-absorbed time-table.

Kakashi's lateness was so bad that Team 7 didn't even expect him to show up until much later. Which actually makes it very interesting that the genin trio were always there to the meetings on time. It would be tempting to start arriving super late to team meetups too until their teacher got his act together. Naruto, Sakura, and Sasuke must be personally invested and interested in their team and their work, since they're always there on time anyway, even knowing that they'll probably be standing around for a long time, even hours long.

It's especially bad since Naruto and Sasuke are orphans who don't have any friends outside the team, and Sakura doesn't get along with her parents and she doesn't have any friends outside of Team 7 either. For Naruto and Sasuke, all they have is Team 7, and for Sakura, she doesn't have a strong family support and pretty much all she has is Team 7. So for a member to so blatantly show that he doesn't care about them will inevitably be hurtful.

Kakashi's bad example is arguably the most harmful to Sasuke, since Sasuke is sensitive and the most perceptive, so he's the most likely to read deeper into Kakashi's lateness and grasp the hidden message behind Kakashi's lateness, which is the realization that Kakashi doesn't care about his teammates, because he can't even be bothered to show up on time for them. Though don't get me wrong, Naruto and Sakura were both very agitated with their sensei's lateness problem too, openly calling him out for it by criticizing their teacher's lateness (not that Kakashi cares about his team's input or feelings anyway).

Kakashi's lateness becomes yet another example of Kakashi teaching his students anti-teamwork. How can the three genin learn to care about their team when their sensei is shamelessly flaunting the fact that he doesn't? At least the three kids show up on time, showing that they are far more dedicated to their team than Kakashi. 

Of course I appreciate honoring and remembering the dead, but Kakashi should pay his respects on his own time, not when the living are depending on his teaching and guidance and in desperate need of his undivided, invested attention.
