One time my work had a “employee appreciation fair” with snacks and games. One game was a cake walk. They asked that if you won a cake you quit playing. My shitty coworker Diane won a cake and kept playing and won a second cake and no one stopped her because it was just a dumb work event. After the fair ended we all went back to our cubes and Diane was gloating about her two cakes.
Another coworker, my friend Laura, told her in front of everyone in our department that she should share one of the cakes with us. Laura pointed out it was only fair as she really shouldn’t have gone back for a second. Our bosses were there and she was really put on the spot, so she begrudgingly agreed to share whilst shooting daggers at Laura. We all cut slices of cake and took them back to our desks to continue work.
I composed an email, the contents of which I’ve forgotten but was something to the effect of “Diane was shooting daggers at you so hard I’m surprised you aren’t dead! Watch out cause she’s probably going to stab you later!” I titled it “STABBED” and sent it to Laura. After a few minutes she pinged me to talk about the Diane situation and I mentioned that I already sent her an email about it. As you can guess, it turns out she didn’t receive it because I accidentally sent it to a totally different Laura! Someone in a different building, in a different part of town. I quickly sent an apology and asked her to disregard the email as it was sent in error. She never responded or acknowledged it in any way which is about the best I could ask for in that situation. This was back in 2008-2009 so I imagine the response would be very different now.
