Strange phenomena isn't it, when you like someone, go out of your way to befriend them, offer your sincere friendship without any reciprocal expectations--and find yourself suspect just because you are offering your friendship and sentiment without any expectation of compensation or reward?
People are actually suspicious when you like them for no reason except that they are themselves, and they reject your affection because it asks for nothing in return. As though they don't deserve to be liked for who they are, but only for what they might be expected give in return. So they suspect that you covertly want something more than they are willing to give--if you just like them, like them. You must be some kind of con.
We always seem to expect that for every affection there must be some unwanted strings attached, real downhome sentiment is not possible.
We humans are very strange. We want to be wanted and loved, but as soon as someone does love and want us, we wonder what ulterior selfish motives they must have, and how they are plotting to take advantage our weaknesses.
No wonder human history is littered with 10,000+ years of warfare.
