I used to work for a guy who cared deeply about all his employees to the point where he bought me a car when mine broke down. Than the recession hit, times got tough, he had triplets, got a divorce and even had to lay off half his company.

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.
