The nose, and the inside of the shin is sensitive. A wallop to the larynx. Car keys yes. Walk along with them ready to hand. I thought I was being followed once, a fairly busy street in Didsbury in Manchester, going along back to my car with some grocery shopping, only about 7: 00 PM. Felt a presence over my shoulder, walking too close behind me. I crossed the road then suddenly sprinted, jumped over a low fence into the car-park, opened my car door got in, slammed it, locked it. A man was standing at the end of the bonnet, leaning against it, staring in at me through the windscreen. Then he turned and crossed over the road again and went back the way he came. So I knew I hadn't imagined it, about being followed. But there were plenty of people about. What did he think he could get away with? The nerve of it.
