Dear Prudence,
I received an invitation to attend a Christmas party from an old college friend. He sent the invitation via social media, the guest list was open, and I accepted via social media. Attending the party will be a few old friends I hardly ever see and my wife and I are looking forward to it. After I accepted I received the following message via social media from an old acquaintance: "Hey I'm wondering if you could not go to the party so that I can attend. I kind of dislike you that much. Much appreciated." It’s hard for me to imagine what his problem is regarding me. I know he went on one reportedly terrible date with my sister. I also dimly recall that years ago he wanted to be friends, but I wasn’t interested and declined his invitations. We obviously don’t care for each other, but I could certainly chat amiably with him at a party. I’m still planning to attend, and I have been struggling with the appropriate response to his message. Should I call him for a heart to heart? Suggest to him someone hacked his email? Tell him I’m going? Another friend thinks if I don’t respond it indicates acquiescence to his request. Suggestions?
