another friend told me that the only reason birthday girl invited me was because her mom made her. I was hurt at the time, though with time I realized the friend probably was jealous of me hanging out with the other girl. She also told me once that the only reason birthday girl ever came over to my house was to see my baby brother. I said "Well, he is cute!" I wasn't meaning to be witty, I just didn't know what else to say to that.
And this girl grew up to be my Evil Coworker who, for the first 2.5 years of my current employment, tortured and bullied me as much as she could get away with. She one day told me that HER area's assistant director didn't like me at all and was only pretending to be nice to me when he says hi. I thought it was the most ludicrous bizarre thing I ever heard and, really, rather random. When he came in later that morning, I kiddingly said (in front of her), "So, Evil Coworker said you're only pretending to be nice to me and don't like me at all" (really, he'd always been friendly towards me and still is). He said that wasn't true, and she said nothing. To this day, she's still a jealous evil excuse for a human being. I've figured out that, other than her husband, daughter and extended family, I don't believe she really has any friends.
