I can't remember how old your son is. Here's what I tend to do with my sons when something like this comes up, and they seem to appreciate my doing it this way. I sit down and talk to my sons and ask them what the options are. What would they want me to do to be of best support to them in this situation? Sometimes they ask me to stay out of it because they can deal with it on their own. Sometimes we've gone to an administrator (in a school situation) and THEY have talked while I simply sat in the room as support. And sometimes that know exactly how they would like ME to handle it. The point is, when I do make a decision on how to act, I am secure in knowing that I am giving my boys the autonomy to handle the situation in the way THEY see fit. That also tends to keep me from reacting impulsively and emotionally which generally causes more problems than it solves.

Try not to sweat tomorrow too much. A decision on how to proceed doesn't have to happen right away. In fact, it sometimes works best to put a bit of space between the problem and the reaction.

Good for you for asking for guidance from your T. I'm sure he'll have great input.
