Haha sometimes my parents do things that are similar, maybe not as extreme as show and tell. Now that I've moved out, I go home to my parents house with my husband on occasion. We live 3 hours away, so it is special when we get to see them. My dad always buys me something to eat, usually not something very healthy (like laffy taffy, potato chips, etc) and points it out like "see look what I bought for you!"
I think its just one of his ways of telling me he loves me :) Trust me, when you do get away from it, you'll miss it someday. I always treasure those moments when I walk in the door and he hands me something, just because it makes you feel like a kid again, and you know you are loved
