Reciprocity doesn't mean that you will get back what you give. You might give good and get back mediocre. Or give great and get back a smack. No accounting for a relationship. No rules. No regs. No guidliess. Each relationship differs from every other one depending solely on the people involved. So you take a gamble and come up winners or losers. You don't stop playing. You just hoping the next time you're gonna leave winners. Right?
