I think he didn't know how to communicate or work on our real issues, so was coming up with excuses. Or perhaps a good offense is a strong defense. And he was trying to hide my questions of OW.
I don't know.
This year, I bought him a gift certificate for a restaurant him and my son like to go. my son also made him lots of cute stuff at school. He thanked me for it.
For Christmas I bought him things from son, that he could do with son (like kite and football) and will continue to do that for future because they are really gifts for son.
