Well, if he scarfed it down...
Everyone has some traits that we have to deal with...I think he sounds pretty special anyway.
A lot can change in a year. I could feel how you mourned your son. In your two cases it might be best for both if he sticks around for a while. I think he wants to be there and I know you want him there. It is cool that he s helping to fix up his own house. I like it.
I'm glad things are going so well!!!
