another take on your son not wanting to talk to his dad isn't that he is angry...just that he doesn't want to talk to him
be careful of putting your emotions onto your children
do you want to talk to people all the time I don't it has nothing to do with being angry and everything to do with just doing something else or simply not being in the mood
ask a teenager how his day was and I bet you get a grunt doesn't mean they are mad just that their mind is occupied elsewhere
