It depends on the types of things you're skipping out on...I know that most people on this forum are making big changes in terms of calorie intake, etc., so if your friends want to go out to a bar and get bombed on sugary drinks while you're trying to jot down every morsel that goes into your mouth, I can see a conflict of interest there.
If you're just avoiding board game night or something because you want an amazing emerging-from-a-cocoon-suddenly-skinny-and-hot effect...well, yeah, I'd say that's a little silly. Your friends already think you're awesome...otherwise they wouldn't be your friends. With 7 billion people on the earth, there's really no use in wasting your time subjecting yourself to people that you don't actually enjoy spending times with, and repeatedly being denied the chance to hang out with someone generally makes people wonder what they did wrong. Just my opinion, but living your life seems like a lot more fun than putting it off to build up to a big reveal.
In any case, congrats on 25 lbs and good luck with your continuing efforts.
