I've been finding a lot of long black hairs in odd places lately. I just found a few in my bathroom. One was stuck to my shirt when I arrived at home. And I also found one in the icemaker at work. Neither I nor my wife have long black hair. My conclusion is that this is either a string of unrelated incidents, or I have a dual personality where I spend a lot of time with people with long black hair and bring them to my work and apartment. If that's the case, I really owe my wife a lot of gratitude for being very understanding.
