Again, I think of it as a dating relationship and when you break up with someone they get pissed and say things, sometimes they regret. Some people are just not nice and don't take rejection well. I think the HC's deal with it better than the RC's because the HC usually does not have the connection and is mature. My son was blessed and several of them still talk to him 2 years later when they see him at events. One actually congratulated him by text after being named player of the year. I thought that was pretty cool. You hope you can end every relationship on a good note and become friends/peers. I think it is also a conversation point to make with your son on how to treat people by showing both the good and bad reactions. BTW, congratulations.
