My name is Ted Pike. I am a worker in a big store. I don't work in the morning. I only work at night. Every morning I come home at about half past six. I have breakfast at seven. After breakfast I go to bed. I get up at about half past two. I have lunch at a quarter to three and supper at twenty to eight. Then I go to work at a quarter past eight. I start work at nine. I look after the store every night. I like my work very much.
