My sister, her family and I (single no kids) were invited to my half-brother's wedding rehearsal dinner before his wedding. We are out of town guests and flew to another country to attend.
We went to the rehearsal dinner and thanked the bride and groom. I don't remember the details of the invitation. The next day at the reception, we were told by our brother that his stepfather had paid for the rehearsal dinner and was angry with us (my sister and I) that we didn't thank him "so we had better go thank him."
Can someone tell me what the proper etiquette is for this? I was under the impression that it was for thanking out of town guests for attending. I am pretty sure his $50 dinner didn't equate to my $1200 flight and hotel and gift. AND we thanked the bride and groom.
