What if P03 can purr? Like via making a soft wirring noise?

Okay so just imagine your with P03 just vibing and being affectionate towards each other. When suddenly you hear a soft wirring noise similar to a cat purring. You know it can't be a cat, P03 hates organics and cats were no exception. Plus you and P03 were the only ones in that room, as far as you knew anyway. 

Then it hit you, what if it was P03 making the noise? You test that theory by placing a hand affectionately onto its monitor. Yep, P03 was defiantly making that wirring noise. Of course, it's confused as to why you placed a hand onto the side of its monitor. So you softly say, "I didn't know you could purr." 

It immediately will start ranting about how it "doesn't purr" and would "never do such an obscene thing". So to calm it down you give it a small peck on its monitor and reassure it, saying you don't mind. It will then lean onto your chest and shortly after the soft wirring noise starts again. You wrap your arms around it, albeit you know your most likely not going anywhere anytime soon.
