Yeah!
And even another angle to consider in this matter of giving with no thought of return. If I get bent out of shape because someone fails to show gratitude for my 'synthetic' kindness when I give 'freely' it shows me I had thoughts of a return. Even to expect a thank you has put a price tag on my gift or obligation on the reciever. Human nature is such that, the other person will probably percieve this obligation subconciously and resent it strongly. I have been married 31 years and love my wife dearly, but she has a desire to be recognized for acts of kindness. After nearly every act of kindness she fishes out loud for gratitude. "There now, wasn't that nice of me"? I have also guilty on this matter of expectations in regaurds to posting things on message boards. I recall brooding over a significantly marvelous post I made quickly slide down the list and vanish into the previous 50 posts without so much as a thank you. This ugly form of soul sickness has caused me to leave communities because they didn't appreciate my unquestionably superior intellegence. oy, what a dumbass I was, and still am from time to time.
I guess when it comes right down to it, there is one thing my wife does for me that she doesen't toot her horn about... She reminds me unconciously how ugly unsolicited obligations or expectations on others cheats everyone involved. Should I thank her for that? mmmmmmmmmmm... I think not.
