An example of the reverse-- being almost "too polite". I had a friend in grad school who was very tall-- around 6'5". When we would go to the movies or live shows he was very concerned and felt guilty about possibly blocking the view of anyone behind him so he would usually end up at the very back of any venue, especially if it was a venue where people have to stand. Another option was to slump down real low in his seat if there was sufficient leg room. He just couldn't stand the idea of diminishing anyone else's view.What I hate more than anything at today's live rock shows is that young people stand on their seats, so unless you have a front row seat, or you stand on your seat, and you're taller than the person in front of you, you can't see anything. I used to go to live concerts all the time in the late 60's and 70's, and people generally didn't do that back then. These days, you have to go to a Michael Buble concert to see people sitting through most of the show, and the tickets just cost too much to deal with that.
