Ja, we had this discussion before. Women just nurse whatever is said in their hearts for months! Then the meltdown happens and the claws come out. It's amazing the kind of things they can say when you let them.
I don't see it happen with guys. I like working with men. In fact working with a male dentist is ten times better than working with a female one. The same goes with co-workers. When men have a disagreement, it's resolved within hours if not days. With women, the bitch-fest goes on and on in a merry little cycle.
At any rate, hang in there, purelife. Just don't take their words to your heart. Remember, you're waaay better than they are so no need to sink to their level.
