I'm part of a fairly wide friendship group through a sporting interest. There's an established core, if you like, but it's been quite fluid over the years as people come and go from the club.
One of the couples on the fringes of the group are getting married. They've invited most of the group, but not me. Which is fine, I'm not close to either of them, although I suppose I was a bit put outnintially to be the only one of the group not invited.
However, one of the other members of the group has invited me as his plus one. He's recently split with a long term partner, I'm recently widowed, so I guess it's convienient. He hasn't done it to "rectify" the lack of invitation, he was talking to me about the wedding assuming I was going and when he realised I wasn't, saw a solution to his problem.
Usually my heart would sink at the thought of being a plus one, you don't know anyone, but all my friends will be at this wedding. OTOH, if they wanted me there, they'd have invited me.
Would it be weird to go? I'm not even sure I want to TBH, but friend is good company and an excellent dancer - when do grown ups get a chance to dance except at weddings?!
