Yesterday, FI and I drove to what was supposed to be a friends wedding. It was over an hour away and was supposed to start at 3. When we arrived at 2:45, nothing was set up, and there were only maybe 20 or so guests, mostly elderly. We waited and made small talk for another 30 minutes, but when no one came out to explain what was going on, I sent a text to a friend from high school, who was a bridesmaid. She was confused, saying the wedding was cancelled! Apparently the bride and groom decided to elope 2 weeks ago, only announcing on Facebook. I do not have a Facebook. I'm assuming the other guests that showed up do not have one either. At this point, I do not plan to send their gift, but do I say anything to them?
