Friends that you had to let go.

I got another friend that I might have to let go at least for awhile. That is #2. I'm noticing a pattern. :) The guy is always angry and bitching at me because of life I guess and the fact that I have already started minimalizing my time with him. He's asking for my wife and I to go on vacation with him (we have never done that but can't take a hint) and will soon retire which scares me because he can't spend a second alone. The guy has zero consideration that other people are different than him or don't appreciate his behavior.
