My Stupid Office Prank Gone Wrong

Last week at work, I got so fed up with my colleague Sarah always hogging the last coffee mug that I decided to play a little prank. I switched out her favorite mug for an old broken one and hid behind the coffee machine to watch. But then, in full view of everyone, she knocked it over by accident! Instead of giggling at my clever plan gone wrong, I felt awful seeing her face drop and hearing groans from the office. I spent half an hour trying to clean up a mess that took five minutes to make. And now, every time someone comes into work with fresh coffee stains on their clothes, it’s all I can think about.
