I was blind,but Iwas ashamed of it if it was known.I refused to use a white stick and hatedasking for help.After all,I was a teenager girl,and I couldn't bear people tolook at

me and think I wasnot like them. I must have been a terrible danger on the roads,coming across mewandering through the traffic,motorists probably would have to step

rapidly on theirbrakes.Apart from that, there were all sorts of disasters that used to occur onthe way to and from work.

One evening,I gotoff the bus about halfway home where I had to change buses,and as usual I raninto something."I'm awfully sorry,"I said and stepped forward only torun

into it again. Whenit happened a third time,I realized I had been apologizing to a lamppost. Thiswas just one of the stupid things that constantly happened to me.So I carried

on and found the busstop,which was a request stop,where the bus wouldn't stop unless passengerswanted to get on or off. No one else was there and I had to try to guess if

the bus had arrived.

Generally in thissituation,because I hated showing I was blind by asking for help,I tried toguess at the sound. Sometimes I would stop a big lorry and stand there feeling

stupid as it drewaway.In the end,I usually managed to swallow my pride and ask someone at thestop for help.

But on thisparticular evening no one joined me at the stop;It seemed that everyone hadsuddenly decided not to travel by bus.Of course I heard plenty of buses pass,orI

thought I did.Butbecause I had given up stopping them for fear of making a fool of myself,I letthem all go by.I stood there alone for half an hour without stopping one.Then

I gave up.I decidedto walk on to the next stop.What was theproblem with guessing at the sound to stop a bus?

A.Other vehiclesalso stopped there.

B.It was unreliablefor making judgments.

C.More lorries thanbuses responded to the girl.

D.It took too muchtime for the girl to catch the bus.
