I was at Mamma Mia a few days ago with dd. My chair was continually kicked during the first half by the child behind. I did the sideways look a few times and her mother told her to stop once, but it continued and a few times I even sat forward in my seat because it was so uncomfortable. At the end of intermission the kicking started again (just before the lights went down) so I turned around, caught the kid's eye (she was 8, maybe 9 or 7) and said "please don't kick my seat, it's very uncomfortable." The mother went ballistic - i ruined her child's birthday, she wasn't really kicking she was just bopping to the music, I should have switched seats so my dd was in the one in that chair (!), no one should ever talk to a child only the parent, etc. I pointed out that she was the one causing a commotion on her child's bday, and that made it worse. So I just turned around, whispered to my dd that the woman was a little crazy, and waited for the lights to go down. reasonable or unreasonable?
