Once I resigned from one ad agency to go work for another agency, my boss started screaming that I was a traitor and that the other CEO (they were on the same board of an association) was stealing his employees. The guy didn't talk to me for an entire week... in a 8 people company. Now we are still in contact, he periodically call me or chat to me to see how I am doing and how is life, he still call me meatball just like when I was working there and everything is good.
