Does anyone have

A totally delusional coworker that "doesn't even know what they don't know" if what I'm saying makes any sense? Today one of my coworkers (who's totally incompetent, sloppy, and always making mistakes that clients complain about and I or someone else on the team end up having to fix) IM'ed me "we back out the interest on X report when we do Y, right?" I replied "no, it's a little different for this one, you just include the interest in this space instead of breaking it out." She replied back "ok that's what I thought, thank you!" Bitch NO YOU FUCKING DIDN'T THINK THAT, you said you though it was the *exact opposite* 5 minutes ago and then contradicted yourself when you realized you'd probably been doing it wrong for months. Ok I have to stop typing now because I'm making myself angry all over again. Tagging pdubs5000 in case she may think this is #relatable.
