Although I am not wealthy, I'm more "comfortable" that some of my friends.  I have paid for a friend to go on trips, to concerts, to sporting events, etc. just because I enjoy his company.  We've been doing things together for 30 years. (for what it's worth, there is no sexual relationship, although I would mind if there were).  He often does things for me, both large & small, that he can do (such as painting my living room)
