LOL! That's funny...she DOES sound like Mimi!!! Heather - I'll have to commend you on your patients with this woman and your ability to be nice to her. Because from the sound of her I know that if I were in your shoes - she and I would be arch enemies. But I can be vicious.
To tell you the truth, it doesn't sound like killing her with kindness will really do much either, except keep you from looking like the jerk. I wish that blowing her off was as easy as it sounds...but I know very well that it isn't always easy to do that. Just keep your chin up and smile when she acts like a witch. Who cares what she thinks about weight loss anyway... what ever her "theories" are, they don't work and YOURS DO
AND I am sure that everyone else in the office knows why she acts that way anyway.
