I know the betral you feel after trusting in someone the way you did.

I had what I thought was a friend that I hired as a apprentance. Trained him for 6 years. When he got his journeymans I gave him his own jobs to run.
Then he took his masters test and passed. I was very proud of him, even bought him a engraved watch.
Less then 6 months later he tells me he is starting his own company and is taking my only journyman with him as his partner, no notice given. The next thing he does is to contact all my customers and tells them that he is now in business and can give them a better price. Loss 2 big jobs to him right away.

Less then 3 years later he and his partner go bankrupt.

I guess that what you call karma!
