I have an acquaintance who I find a bit judgmental about other people, specifically how bright they are. I get the impression that she thinks that intellectually I am about on her level. We were having a discussion about a mutual interest and no less than 4 times she pulled me up on the use of a particular word which, admittedly was incorrect but is very accepted in normal conversation - along the lines of saying Hoover rather than vacuum. Most people probably know that it isn't quite correct but most of us say it (don't we? -say yes!). The fourth time she said something about only joking and I muttered that it could get a bit wearing, I am not sure if she heard me.
Today, several months later she made reference to someone else feeling the same as she does about this usage. The comment was directed at me but not in a nasty way. It really pissed me off, really I suppose because it had so pissed me off before so I said that in the end it could be just rude to keep on correcting people in that way. She just said "thanks", it obviously hit home a bit. I dont generally go out of my way to upset people but I do think it's rude to correct people all the time and I find it unnecessary. Am I a cow?
