I don't know what made me remember this but I had a coworker once with whom I had developed(I thought) something of a rapport. Well one day we were in the nurses' station and I jokingly made a comment about her not working hard. I forget my exact words but it was something along the lines of are you hardly working or working hard. You know that lame joke, well not that lame but it was harmless like that. Well a few days later, guess what I got invited to a meeting with her and the charge nurse to discuss my attempt to slander her! She said that she felt like I had a low opinion of her as a nurse and my comments left it open for people to believe that she was not a hard worker. And I was attempting to destroy her reputation as a nurse. As broadsided as I was, I apologized profusely for my faux-pas but she wasn't in a forgiving mood. So *shrug* what could I do? Obviously we weren't as good of friends as I thought or she might have given me the benefit of the doubt. Also she must have had a massively low self-esteem or insecurities if she was that bothered by my little joke. I just moved on. I can remember being quite annoyed at first but it's funny now.
