Can you help me?
What seems to be the trouble?
There is something wrong with my bike.
Oh. The brake seems to have become loose. That's dangerous. Without a good brake, you can't control your speed. Accidents are more likely to happen. You'd better have it repaired as soon as possible.
Where can I find a repairman?
There is one at the corner of the street near the post office. It is about 150 metres away.
Will it take long to get it fixed?
Just 15 minutes.
