I'm refusing to buy something from my brother and his wife's registry, so I just made a charitable donation on their behalf
Why did you make a charitable donation instead?
I just don't want to see their faces at the wedding, and I didn't like anything on the registry.
Even if you don't want to go to the wedding, you should probably still have picked something from the list. It would be nicer to treat them the way they were expecting.
But they have a bunch of dumb things on there that they probably don't even need.
I understand that you think the items aren't very useful, but if you still have time to change your mind about this, I suggest buying a gift from the couple's registry. It's possible that they really need some of these items to help get their life started.
