I wanted to double back to this comment because it brings up a valid point.
I've been disappointed by most people I've called "friends" in my 60+ years of existence. It seems that because I'm a handy guy and I can fix and build just about everything, and I'm willing to help anyone out, that they ultimately see me as some sort of worker rather than a friend, and that's probably my fault as much as theirs. Most people are ultimately in it for what they can get out of it and that's true as far as friendships, relationships etc. Even women I've been married to and been in long term relationships with.
There are a few exceptions to the rule and I do have a couple of friends who don't meet that particular criterion, and my current wife also does not take advantage of me and never has. But that doesn't change my overall lack of trust in most people in general, nothing ever will change my opinion that until they show themselves to be otherwise, they're looking out for number 1 and if it's at my expense they won't give a second thought to throwing me under the nearest bus.
