Servo, sometimes it is just a matter of not pouring fuel on the fire so to speak. If people in your family try to aggravate you, or as we say at PC trigger you, then not reacting is the best policy. Sleep on these things overnite. Just don't get drawn into the drama. It doesn't seem to make you feel better.
You already are starting to make a new family at PC in my opinion. At least you are communicating with us.
It's a good start.
