I have a cousin who I unfortunately had to invite to my wedding. He has mental disorder (not sure which one), and although he's functional for the most part, he comes off as an annoying, creepy, pervy, immature, simple minded, socially awkward, weirdo. He's friendly enough and I think he's harmless, but he chooses the most awkward, eccentric conversational topics. Like Bevis and Butthead (YES seriously! He ALWAYs talks about freakin Bevis and Butthead! I actually think those guys might be his role models, cause he kind of acts like them!) and feeding his pet snake. More importantly, he totally has the creepster factor going on. He always seems to be checking out my sisters and I, and saying things that make us feel uncomfortable in that sense too. After talking to him, you can tell he's got something wrong with him mentally (or has taken waaaaay too many drugs), so that at least gives him an excuse, and I guess I can deal with that. But he won't wear deodorant! THAT'S where I draw the line. I am not close to him and never talk to him unless it's a family function (he shows up to faithfully to every one). So I don't know how to tell him to wear deodorant. Even if I found a way to, he probably wouldn't do it. What do I do?!....
