I'm going to tell my cousin I don't want his shitty presents.
Why all the hostility towards your cousin?
I don't like his taste in presents.
He tried to give you something nice. I think you should just say thanks and move on.
It would have been nice if got a really cool gift.
I understand you would prefer something different, but Santa Claus can't read minds. He went to all the trouble and expense to shop and wrap your gift -- it's hurtful and rude not to show appreciation for his effort and thoughtfulness.
