For a minute I think I’m starting at my twin; I’m half asleep, only to remember that I’m a triplet and we don’t look alike. One of us blond, one of us short (that would be me), and one of us a boy. I blink, I shake my head, I rub my eyes, I lean to a colleague and whisper “I think I’m seeing things.” They do a double take. They blink, they shake their head, they rub their eyes and whisper back, “I think I’m seeing double.” A man walks in and gives a yelp. There’s no explaining this one.
