I Like To Observe People

A co-worker whom I do not like and probably doesn't like me introduced me to a new associate as they were in passing. I can bet my bottom dollar that that person told the new associate not to talk to me, or that I'm mean, stuckup and whatever else people say about me behind my back. I say this because its happened before. An associate will converse and chit chat with me. Then once they are around another person ( who doesn't like me) they stop talking to me and/or their demeanor towards me changes.

It's funny how I thought high school behavior ends at 18...
