When you are overweight a lot of people just put you in the "fat" category and stop thinking about it; and, it's not until you lose a lot that they are forced to notice. When I lost 130lbs years ago no one noticed or said a word until I had lost 60lbs. Your grandma noticed because she loves you and is more in touch with you. I did have someone at the gym notice but I think that's because of the context. My mother wouldn't say anything, ever; she's just like that. My dad, now gone, would always notice. Personally, I'm the self-referring type and I actually don't like it when people say anything. Maybe I just don't like it that they are looking at me that closely when I don't know it. Ha. I'm just a kind of private person. You are doing great so look in the mirror and give yourself a big congratulations for all the fat no longer there.
