Little kids can be like that
My little cousin went to a Cubs baseball game maybe 2 years ago and he got to go see a player for the Cubs when he went up to the stands to sign stuff and greet fans.
Well, this player (forgot who it was, I would have to ask my aunt) signed my little cousin's hat. Everyone else was happy for him but my cousin, being 4 at the time, proclaimed angrily "That guy wrote on my hat!!!!!"
We went to a RailCats game in Gary on Friday too. The newest edition to their family (he's 2) was also quite a joker. That's a story for another time though
