My BF and his coworkers are constantly playing practical jokes on each other. Usually it is harmless but irritating stuff like putting soap in the one guy's relaxation fountain, backing into each other's cubes and farting, or switching drawers in a desk or filing cabinet. But tonight my BF forgot something at work so we went in to his office on our way out to dinner. After he grabbed what he needed, he pulled a pair of women's panties from his hoodie pocket and stuffed them into a mug on another guy's desk. I was like, what was that? And he said, "oh, so and so put them in my pocket today. I was wondering what he was doing in my office for so long earlier." I laughed at first, but then I started to think about it some more. What if DBF never realized he put them in there and I found them?? I can't even IMAGINE how I would react to that... It actually made me pretty mad - in my opinion a practical joke is NOT something that could split up someone's relationship. I am just glad I don't have to find out what would have happened if I had found them in other circumstances.
