I had the experience today of overhearing what a crazy person was saying on the street and completly understanding what she was talking about. She was on a corner standing astride an old rusty beach cruiser when a BMW blew past her. I was pulling up to the corner, and it took her a few moments to get her thoughts together. After the BMW was far down the street, she addressed it as if it was a person who'd been rude to her: "Well. SOMEBODY'S in a BIG hurry!" Then she turned to me and asked how to get to Houston. I said, "Houston?" and she said, "Mmmm, mmmm." ...long pause... "Hudson." I began explaining to her how to bike there, but she started riding away in the direction I pointed before I could really get into giving directions. So then I stood there on the corner by myself, yelling directions at her back, now my own little version of crazy for someone else to observe.
