I love it when a ball knocks someone's drink down or something.. I mean, why would you even come to a game if you're not gonna watch? So, if someone watching gets hit/hurt, I feel bad, but if they were talking and not watching or something, I could care less.
That's gotta hurt big time! I don't have to worry about bats hitting me though since I don't go to baseball games or for any other game for the matter at least on a regular basis.
