The young girls trying to get the attention from the players are the worse. Speaking as a former, and rabid, fan, I found myself jumping out of the seat sometimes. I was passionate and excited about the game then. On every occasion that I did jump up, however, I was almost immediately concerned for the people behind me and quickly sat down. Its all part of the game.
Some parents have no choice but to bring their kids.
Again, part of the game. Its not that bad. If they aren't going to watch the game, they need to go home. Some of us WANT to see an incredible shot or a beautiful save, instead of a rear-end in our face. I think they should start announcing it over and over, then maybe people will think twice before they are so rude.
