You have this backwards, or at least, you're leaving out one very important aspect, namely the group's responsibility to make things clear on their own.
Honestly, that was one of the things I initially posted but as the discussion wore on and with the admission by him that this happens a great deal to him, I think I kinda came to the realization the lack of communication (or ignoring of the signs, as he also claims to do) is something for which he seems to bare responsiblity.
Could be a bit less judgmental, don't you think? Me, I think it's important to be fair with a group, get a genuine feel for them, before you decide to leave or not. Which may happen, but if you're going to knock a guy because he didn't just up and leave, but tried to give the group a chance, then well, I'm concerned that you're the one with the bad expectations.
Sure, when it happens once or twice. To read his posts, though, this seems to be an epidemic in his game experiences. I'm all for giving someone the benefit of the doubt. His posts remove more and more doubt as he becomes more explicit.
