Totally agree - I don't comment on it either way. I can tell when someone who I haven't seen in a while is surprised that I'm not complimenting them on their weight loss. However, it is so ingrained that recently I saw my brother for the first time in years and the first thing I said was, "Did you lose weight? You look great." As soon as the words left my mouth I wished I could have taken them back. My parents were with me and both commented on how they couldn't believe I said that (I preach to them about the dangers of diet culture, etc). Just shows how deeply ingrained some of our reactions can be. Great piece!
