Yes, 65 lbs gone is fantastic, and I'm sorry that more people haven't commented on it. But, I agree with photochick that many people can't decide whether to mention it or not. If they mention it, they're afraid you'll think that means that they thought you were fat. If they don't mention it, there afraid you'll think they think you're still fat, etc, etc. I've even been there myself, until I lost weight and realized that it was a lot of work and effort and I wanted it to at least be acknowledged.
Sooner or later though, people won't be able to ignore it and you will hear so many comments on it that you will get tired of them. Just keep doing what you're doing and don't let the lack of comments/compliments right now get you down.
