HOw scary for you hun.

So... an alternative. maybe try this: Get a price of paper and draw the situation: Jack and Luke on the front step. Then draw you with a very sad face. He might scrunch it up but it might sink in. Kids are visual. You don't have to be an artist..... just stick figure.... point out who is who. sometimes doing something different in itself has impact. I have a tendency to banshee too.... and just like if someone was yelling at me I would tune out too. i know it's so hard. good luck!
I like this idea. Might try it
