K: When I grow up, I don't want to cut my hair
Me: Well honey, you don't have to cut your hair if you don't want to
K: Yes I do. You have to cut your hair when you grow up.
Me: No you don't K, you never have to cut your hair if you don't want to.
K: Yes you do! If you don't cut it, it will touch the toilet!
Me: (trying no to laugh) Well, you can always just move it out of the way so it doesn't touch the toilet.
