I can kill people, or cause great pain. You eat me. I can mean you’re crazy. I hold things together. I help climbers stay safe. I can replace a swear. And I’m on a violin.
People with nut allergies can die from eating nuts. Being hit in the nuts hurts (I speak from experience. Painful, painful experience). You eat nuts (unless you’re allergic, in which case you should run away). If someone says you’re nuts, it doesn’t mean you’re a peanut or an almond. Nuts and bolts hold things together. A climber’s nut or chock wedges into a rock. Instead of swearing, you can say, “Aww nuts!”. And finally, the nut on a violin is a small piece of hard material that supports the strings.
A man is running across a field at night clutching something in his arms as several other men pursue him. He looks back and sees they’re getting closer. In a final burst of effort his pursuers catch up and bring him crashing to the ground. His pursuers stand over him but do not touch him or take what he was carrying. Why not? Who was the running man?
A thought in your head. You can hear it, but no one else can. Unless you read minds, but then you’d have bigger problems, like figuring how how to remain sane in large crowds.
