Why should I give $200 of my hard earned wages to people who won't permit me in their home or speak to me? I wouldn't do it for someone else who treated me with such contempt, so why should their being related to me make a difference?
Bravo, Lady!!
I was invited to my nephew's wedding a few years back, and being DF'd and remembering how he had said he never wanted to hear from me again in his last communique, I decided NOT to bother going, or giving them a gift. Kiss my ass, quite frankly.
