that's sooo great! congrats!!!!
i had a similar experience recently. we had went over to my boyfriends parents house, and one of the guys my boyfriend works with lives next door to his parents. now, my boyfriend sees this guy daily, but i only see him every so often. the last time we went to brandon's (my boyfriend) parents house, the guy he works with comes up to me (he hasn't seen me since halloween) and was like 'wow tracey, you're looking great. you've lost a bunch of weight!" and i had really only lost about 25 pounds since the last time he saw me. (this was on new years eve.)
but that just felt SO good to hear that someone noticed.
my boyfriend lives with me, so he sees me too much to really notice any slight changes. i guess it's a good thing to have those people around that you only see every couple months or so..to give you that added boost of confidence!!
