Wow, Mighty! I just caught up. Way to go handling his emails.
He didn't bait you a bit.
I went through something similar with D20. When she was still in high school, Smokey would blow at her about her grades and she would react with a plethora of obscenities. He would, then, talk to her about her "mouth" and her disrespect and so forth. He would, of course, never touch on how his behavior had played a part in all this.
In hindsight, all I could do was be there for my daughter. She has some things to work on...but, she is sorting it out.
I like how you shielded your son, to the extent you were able...I remember being in that position of interacting with Smokey and realizing that...when he interacted with me, he was more likely to leave the kids alone. Seems like he always had to pick on someone, I'd rather he pick on me.
You're doing great. :-)
