     Some people remember things by writing to themselves. Then they leave the notes in obvious places,

such as on the table or on the floor in the middle of the living room. I don't think I like to write notes to

myself. Most of the time I lose them or forget to look at them until it's too late. I prefer to use an alarm

clock to tell me what I should do. I have ten alarm clocks in my house. They could tell me about things.

For example, if I have to make a telephone call at a certain time, I'll set an alarm clock to go off a few

minutes early and put the clock by the telephone. Or if I want to watch a certain television program, I'll

set an alarm clock at the right time and put the clock on top of the TV set. I can remember almost

anything if I use my clocks. However, sometimes an alarm clock goes off and I don't know what it means. I always remember setting it, but not why I Set it. If the clock is by the telephone, I know I may have set

it to tell me to call someone, but I can't be sure. I might have set it to tell myself that somebody was to

call me at a certain time.
