The thing that chaps me in this case, is that my SD is sweet enough that she actually wanted to thank me, but my W opted to not allow that to happen.

This is all mind-reading and making things up to suit your narrative.

Take it just as it was-you were thanked for a gift.

Let me give up the need to know why things happen as they do.
I will never know and constant wondering is constant suffering.
