Ironically we have two friends whom we did NOT want to know about our wls because they have both had one and are both know it all's. We don't want advise from them and we don't want to hear what they did or what THEIR Dr told them or that our Dr is stupid for doing this or that our that we should (or should have) give to their doctor. Besides, both of them are not eating how they should be and have gained a lot of weight. Fine examples.
We have not come out to everyone though. Some things are just not everyone's/anyone's business. But for those that we've told they have been supportive.
