There's nothing wrong with being a good person. Nothing at all. I've given away snakes to several people to give them a hand up, or replace an animal that they've lost. I've done this privately, with no need to be publically acknowledged for it. Only the people who I gave those snakes to, and I know about it, and the details. I expect absolutely NOTHING in return from any of the people who received these animals (and kindness) from me.
It becomes less an issue of being a good person and more of an issue of being self-serving when you use that kindess as a sort of "blackmail" because someone didn't return the kindness to your satisfaction and then run to a forum to "report" just how your kindness wasn't reciprocated. It makes one question the genuineness of the original kindness.
I wonder if Kristy had known that the kindnessess would be thrown back up in her face at a later date, if she would have gone through with the transaction. She hasn't presented her side of the story, so who knows?
Morphie, did you send Kristy a link to this thread so that she can respond?
