There are something wrong with my computer.
Really, what's wrong with it?
The computer doesn't work when I push the power cotton.
Oh, do you use your computer often?
Yes, I don't know why it doesn't work this time.
Don't worry. Have you got receipt with you?
Yeah!
We'll go to your house and repair it on Tuesday. Ok?
OK, I'll expected you around 2 o'clock?
See you then.
