Weird B&M friend question...this might be kind of long...A GB of mine had surgery on his teeth about 3 years ago. He was pretty standoffish about it and almost never smiled afterwards because he was embarrassed about it. Not that he had bad teeth or anything but when we did catch him laughing, he had new teeth and they looked great. We are guessing that it was something deeper than just the surface of his teeth, but whatever.Fast forward to last March. He said he had to undergo some more surgery and would be out of commission for a while (but never said anything about his teeth/mouth). It got postponed twice and long story short he couldn't make my wedding. No problem, he sent a card stating as such and we completely understood. He did tell us that he would be out of work for at least 6 weeks.Fast forward to now and none of our group of friends have seen him in almost a year. When we would contact him his only response would be "I can't/won't come out right now". He wouldn't accept invites to come out nor would he allow any home visits (single 36 year old man) He went to Brewer, Packers and Bucks games by himself (and posted pictures on FB), he wouldn't offer any insight as to what was going on. 95% of our "clique" have been friends since grade school. We're a pretty tight-knit group.His name is Chris. Often we would joke that he would come back to us as Christina, since he was hiding so much. Well, a few GBs were bowling tonight so I went to join them and watch Marquette #### the bed. Halfway through bowling Chris showed up. He looked the same and everyone was saying "Holy ####! How have you been?! We haven't seen you in almost a year" All he offered was "I've been away"I didn't press and just asked how he had been doing. I figure that if he wants to tell me/us something, he will. He had 2 beers and called it a night and said "I've got to get back into drinking shape"I'm not sure what I'm asking, but has anyone ever dealt with a close friend that dropped off the face of the earth for medical reasons, only to show up and not mention anything? This guy does not do drugs, he does not date at all (men or women), doesn't do anything that would be cause for concern, and doesn't live a lifestyle that would lead to a year+ long procedure....I just don't know. I don't want to violate his privacy, yet I'm concerned for my friend.SOrry for serious-ing up the thread again
