I have a very good friend from high school whose wife does not care for me. I got an invite to her baby shower today and I'm flummoxed. I could maybe understand if it was a couples shower, but it won't be. I've met this girl one time (at the wedding) and she was rather rude. I'm not attending, and I'm sort of unsettled that I was even invited, but I didn't know if I should still send something. I was planning on sending a card when their child is born. Is a card appropriate or do I need to send a gift because I was invited?
