A long time ago, I sold a Craftsman 8" tablesaw to a friend for a song. It was a saw that my dad had bought when he was building our house, and it had made its way to my garage over the years. I had always regretted selling it instead of just giving it to my own son. Well... said friend is in the process of divorcing his wife and preparing to clear out of Dodge. In conversation with him, I offered to buy the saw back for whatever price he wanted - just because I wanted to pass it on to my son. Low and behold, he says "No Way!" - "I'll just load the saw into my truck and take it over and give it to your son - that's how it should be".
I know - it's kind of a dumb little story, but it's pretty big for me.
