I’ve posted a lot about these situations in different threads, but one of my favorites was in college when my roommate forgot to put the bandana on the doorknob to signal not to come in, and when I did he was tugging it while watching porn. We were both so surprised. He was so close to finishing that he just kept going and I saw him bust all over the place standing basically right next to him. He didn’t make any kind of big deal out of it. He just said, “my bad I forgot to put the bandana.” I just said, “it’s all good.” After that, nothing mattered anymore. We abandoned the bandana and pretty much all associated acts of “discretion.” It actually made being roommates so much easier for the entire rest of the year!
