     I felt very sad because I was not able to get the ticket to the film Hero last Friday. I learned from the

newspaper that tickets could be bought at the cinema box office in Richland Hills any day between 10:00 a.m.

and 4:00 p. m. Since I work from 9:00 a. m. to 5:30 p. m., the only time I could go to the cinema was during

my 45 minutes' lunchtime. It is a pity that the cinema is on the other side of the town and the bus service

between my company and Richland Hills is not very good. But if you are lucky, you can make the round trip

in 45 minutes.

     Last Monday, I stood at the bus stop for 15 minutes waiting for a bus. By the time I saw one come round

the corner, there was not enough time left to make the trip, so I had to go back. The same thing happened on

Tuesday, and again on Wednesday. On Thursday my luck changed. I got on a bus right away and arrived at

the cinema in twenty minutes. But when I got there, I found a long line of people at the box office. I heard

one man said he had been waiting in line for over an hour. I found I would not have enough time to wait in line.

I caught the next bus and went back across the town.

     By Friday I understood my only hope was to make the trip by car. It was expensive, but I felt it would be

worth it to see the film. The trip by car only took 10 minutes, but it felt like an hour to me. When I reached

the cinema, I was delighted to see that nobody was waiting in line. But I quickly found out that it was because

they had already sold out all the tickets.
