An ex-roommate of an ex-roommate of mine breezed into the store, thinking it was a used book store. She harrumphed a bit when I told her we were a comic book store, and then said "You're...Adam, right? You used to live with...Harriet?"
I have never lived with a Harriet. But I know who she means.
And, normally, convention dictates that I would say "Yes, and you're Sarah." or Jennifer or Ayanna or Chloe or whatever name she has.
And, usually, the problem is usually that I don't remember names well. In this case, though, I remember that she went by an unfortunate name that she gave herself. Something really pretentious that sounds both fake and off-putting. And I don't remember what it is precisely because one of my exes and I made up a game where we tried to come up with even worse names in the style of her name. And I'm not enough of a jerk to say "RIght, and you're Pennywhistle Fartbox", even though that's the closest I can come to remembering the name she goes by.
Now, I have many friends who don't go by their original names for a variety of really solid reasons. But this was purely because the person thought her name would help her Get Famous, and it was As Ridiculous as the names I'm giving here:
Green Bean Muffintop
Pistachio Shell Moonbeam
Strawberry Quick Milkshake
and Drycleaner De Plum
