I had a bit of the opposite experience when an ex-colleague passed end of last year. About 25 of us from one company he worked at showed up to the wake and it was slightly awkward to tell the family and friends who we were and what connection we had (he hadn’t worked there for about 9 years and I was the only person who still worked at the company, but we all turned out because we genuinely cared about him).
But talking to his wife and family in the receiving line was super-awkward. I hope they found it at least epsilon comforting.
