She poops at parties?

Went to a party last night where I didn't know anyone. It was my husband's friend from a long time ago and they were reconnecting. I was kind of a party pooper. They were all drinking and doing shots and while I wasn't trying to avoid the people I had to get away from all the smoking. I was getting a headache. One other person didn't smoke and she sat and talked about her cats for 4 hours. Now I don't hate animals but I don't have any. I don't sit and go on about my kids either. I tried to change the subject but somehow it always ended up back to the cats. I feel like the others probably thought I was this lame person but I didn't want to eat anything because of the calories and I didn't want to drink because not only was i driving but the calories and slow metabolism it causes. Does dieting make me boring? I'm usually the fun one! Ugh!
