Oh I so agree with the children part.. I have been to sooo many shows where people bring children under the age of 6 with them.. if they are good kids and sit through the show then great, but I have witnessed so many times kids having to go to the bathroom, or they are asking for a snack, or they can't see.. etc.. if its not a Kid show i.e beauty and the beast, etc.. then leave the kids at home.
and of course the late comers! How hard is it to get there on time? I can't even count how many times I have dealt with late comers either in my row or the row in front and worst of all when they are behind you and they knock you in the head with there coats!
And I have to apologize to the shorter people, I'm 5'10, and always try to sit so that people can see behind me, but at the same time can't really slouch to much because then my knees are pushed into the back of the person chair in front of me, I usually try to get the aisle seat.. but I do try my best to be as consderate as possible! I promise!
