I do it to a certain amount cos I have to in order to do ok at work etc.
I try to fit it in too but some expected behaviors are so nonsensical I can't follow them. For instance, staying in the theater until the very end of the credit roll. I know people do it out of respect, but it's not like they're gonna remember any of the crew's names. Oh and I can't ask people how are you doing because I expect an honest answer.
