When a coworker asks you who you spoke to and you have no idea what their name is.
Then you try to charade what they look like, then your coworker starts going down a list of other coworkers names and you’re like “Honey, I don’t know anyone’s name, not even yours. Except of Charley from accounting, he as the same name as my nephew, he also kinda looks like him, but as a grown ass man. Then you wonder what would happen if they met, would they become friends? They don’t have much else in commun though… anyways, I don’t know who I spoke to, sorry.
Edit: I didn’t proof read my post until it was posted.
Oh hell yeah. And it's even worse when the coworker then finally figures out who you meant and goes "oh you meant [blank] why didn't you say so?" and you're so relieved that the uncomfortable situation has solved itself already that your brain checks it off as "completed" and moves on to the next task while still not getting the name that was just told to you five seconds ago.... but then it is too embarrassing to ask again so you just roll with it and hope it doesn't happen again (which it of course will).
