You decide to trust your instincts. You and Paul have been friends your whole life, and you should probably make some attempt to clean your mess up. "Come on over, man." You say goodbye and hang up the phone. You slide off your shirt, taking another look at the jungle of golden fur on your chest. You run a hand through it contemplatively, then throw on a long sleeved shirt. Last but not least, you put the ring in your pocket. Best to ease into this.
A few minutes later, Paul buzzes up at the lobby off your apartment, and walks in almost as soon as you open the door. "I think I have a disease or something dude. You need to take me to the hospital or... dude, I don't even know." You see that his usual smile is not on his face and his eyes are wild and serious. "Just calm down Paul. I-" Without warning, he pulls up his shirt. "All of my body hair fell out dude. Or like... it didn't fall out... cause like... it wasn't on the couch or floor or... anywhere. It's gone. Are my eyebrows still here???" His round stomach is a lot smoother than the last time you went swimming. You grab him by the shoulders and sit him down.
"Okay, I'm not sure how to say this, but that's my fault." Paul looks at you, confused, but a little more calm. "Did you put Nair in my laundry soap or something dude? What exactly are you talking about?" You sigh and point to your eyes. Paul stares blankly. You decide a direct approach is probably best. "I took it from you by accident. I was switching our eye color, and that happened too." You pull up your shirt and show him how thick the hair on your stomach is. "Dude. What. The. Fuck." Paul states. You continue. You pull out the ring out of your pocket, and place it in your hand. "I bought this ring, and it has the power to... switch stuff between people. Crazy, I know. I don't even know why I bought it. But... it actually works." You explain how the ring works and Paul nods, an unreadable expression on his face.
"So, I can't do anything till tomorrow," you finish. Paul looks at you hard. "Well, I mean I'm not broken up about losing my hair or eye color dude... I wish you had asked first but let's move on. Consider being a furball punishment enough." His stony gaze breaks and the trademark smile is back on his face like usual. You're grateful he seems to be taking it in stride. "Besides, I want to give that ring a spin. Maybe that whole one-switch-a-day thing is like... a per-person kinda deal, you know?" He holds out his hand for you to give him the ring. What should you do?
