Two friends of mine from grad school got married a little over two years ago in Vegas. Everyone in our school got an invite, but with no details as to a time, date or location they were more preannouncements than invites. Nevertheless we scored around their registry and sent a pretty cool gift (they wanted a Monopoly set but knowing they were huge Doctor Who fans we gave them the special themed sitting). About fourteen months later we get a one sentence thank you.
Fat forward to today. I just received a mass email invite to their re-marriage party. They hadn’t received the blessing of the church for their first marriage and are now celebrating the fact that they have. The invite included a link to a new registry (at a more upscale store than before). Making it to this ceremony is out of the question so am I expected to send a second gift?
