AIBU to think that (with the exception of couples), talking about your plans in front of someone not invited, is at best rude and at worst, spiteful? Same goes for talking about an event afterwards in front of uninvited others (and I would even extend to posting photos of and raving about events that only select people were invited to on FB, but perhaps that’s overly sensitive?)
I see this all the time and it really grates on me. I would never do this and don’t understand why others do?
