A 5 year old's girlfriend

Harry said a couple weeks ago that he had a girlfriend at school, her name is Arshyia (she's beautiful, stunning really.) Andy of course asked, and I was thinking, "What does that mean she is your girlfriend?! What does a girlfriend mean?"
Harry said, "It's when a boy has a friend that is a girl". :) Although when he was asked if any of the other girls were his girlfriend he said no. He did say he thought she was pretty.

This morning Andy asked if Arshyia was his girlfriend and he said no. Andy said why not?
Harry: "We don't agree on things"
Daddy: "What do you mean, like what?"
Harry: "We don't agree on numbers."
Daddy: "What?"
Harry: "We don't agree on numbers, I'll say 1 and she will say 8."
Daddy: "Oh, okay."
