The "get over it or die mad" is one of my favorites.
Another issue I have is having someone ask why someone else couldn't do whatever they were asked to do...If I ask someone to join a group of us for dinner and they say they are unable, I don't ask why. Why would I?
Some others ask what their excuse was, how would I know? I didn't ask for their justification. (not just for dinner - for playing golf or tennis, attending the theatre/movie, whatever) Really, it's none of my business, they might offer that they have other plans...but I don't ask for their excuse. Some seem to think there must be justification, I don't, sometimes I just don't want to do "whatever" and I just say I am unable.
