There are something wrong with my computer.
Really, what's wrong with it ?
The computer doesn't work when I push the power botton.
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.
