"I've got my family to feed" - Latrell Sprewell
I hate when people make it like its a feed my family choice like they live in a hut somewhere. Above a certain level of income the "feed my family" excuse is simply that. An excuse for otherwise inexcusable behavior.
Just be nice to people, its not that hard. The world especially the tech world isn't a zero sum game.
He made promises to me when times were good that he couldn't keep when times were tough.
He cared about me, and yet, for a long time I thought he screwed me when he went back on a deal he made with me.
Lots of people are nice, but back them into a corner (even only in their own minds) and their survival instincts will kick in.
It is simply naive to think otherwise.
Protect Yourself, especially with Nice people who you trust.
