Lisa was a very bubbly girl as a child. She made sure to be friendly to everybody as she was always told "You never know what somebody else is going through and maybe a smile will brighten them up even if it was just for a second". Lisa met Cory at preschool at the age of three. She started a bit before him as her mother needed to work. She comforted him as he cried about leaving his mother. She understood how he felt. 

She met Shawn when she a bit older. He was trying to show off. Trying to jump down from a wall. Liza offered him her biscuits if he didn't jump. He took her up on her offer. She saw him again later at the zoo.
