A friend of mine (of 25 years) and I got together to morn the loss of a mutual friend. I offered to tune her piano for free just to be nice. The subject of cuddling came up and she revealed to me that she is a professional cuddler. She then offered me a free cuddle. For some reason, despite the fact that I would cuddle her and do the tuning, the idea of these two actions being some kind of exchange makes it impossible for me. I guess I've discovered a deeply ingrained creed toward free love.
