LOL! U got that question from crazy english. Richard lederer. here is another one from his book. . When a house burns up, it burns down. You fill in a form by filling it out and an alarm clock goes off by going on.. . When the stars are out, they are visible, but when the lights are out, they are invisible. And why, when I wind up my watch, I start it, but when I wind up this essay, I end it?. . Now I know why I flunked my English. It’s not my fault; the silly language doesn’t quite know whether it’s coming or going.
