"My sister, my (now) husband and I were all in the same graduating class. Plus, my husband’s best friend.
Best friend’s name is something like “John Smith”. Very common. He was very popular in HS. Super nice guy, stood out in a crowd- if you didn’t know him you certainly knew of him. Even in a massive school.
So anyway, the 20 yr reunion rolls around, my sister is the only one who wanted to go. She called right after, very upset. Apparently there was a huge memorial wall for John Smith, who had just died! None of us knew! Awful.
My husband was like, huh. But we just saw him? Called him up and was like “Hey dude, are you dead?” No. Not dead. Surprised, but not dead.
Anyway it turned out the much less popular other John Smith was the one who died. They made a lovely memorial for the wrong guy, who was forgotten totally.
We still run into people to this day who see him and are like “Hey… aren’t you supposed to be dead?!”"
