I have so much trouble eating around friends in social situations - probably because I hang out with mostly guys and I always want to be that laid-back, fun girl who doesn't worry about weight or count calories. So I always wind up eating more than I intent to and make some pretty bad choices.
One of my closest friends is in the states on vacation after spending a year and a half in the Peace Corps in Bolivia and we had a big barbeque party for him last night. Instead of having a GIANT fresh sausage and potato salad, I had a grilled veggie burger and a big salad. I did indulge in some chips and a delicious homebrew stout beer, but I was so proud of myself for making such a good choice. And at the end of the night, when most of my friends were uncomfortably stuffed and a bit drunk, I was feeling good.
Like I said, a tiny thing, but it feels like such a turning point for me - like some sort of public acceptance that I'm trying to eat healthfully and be good to my body.
