My sister that is estranged from pretty much my entire family just sent us a Christmas card with photos from her court house wedding that we didn't know she was having and we found out about because she is still Facebook friends with my husband. The very last line of the Christmas card says thank you for your love and support, but if you so wish money is preferred. I am stunned and can't believe how rude she could be. That to me is very poor wedding etiquette. I honestly don't know what to say.
