Have you ever made a serious breach of office etiquette that made you want to call in sick? This hilarious conversation on Twitter has people sharing their stories of times they’ve screwed up in the workplace and ended up looking pretty unprofessional.

One user named Maurice started off the story round with a time he was annoyed when a business contact spelled his name wrong, so he called them out only to be told that they were just following his lead, and to take a look at his own signature. A lot of people were reminded of their own fails, and this thread was born.

Some of them can be blamed on Autocorrect, which has been “ducking” us over since its invention. It’s usually fairly benevolent when you send an unintentionally crude message to a friend and you both giggle like you’re 12 years old, but when you send it to the whole office, it can feel like the equivalent of having your pants rip while you’re giving a presentation. As much as we resent autocorrect, though, we’re not much better off without it. When you simply mistype, forget words, or send an email to the wrong person, unfortunately, you have nobody to blame but yourself.
