One day I came home from school, changed my clothes and got ready for work. I work at a local restaurant in town as a cashier and waiter.
I went to work feeling   36  . And to make matters worse, I was busy that evening. It' s the same thing over and over again. 37 with customers who complain about their food andwhere they are 38 is too big or too small. Little things like that tend to 39 a lot of us 40 but we manage to deal with it.
Three elderly ladies walked in and sat by the windows. It happened to be the very   41  near where I keep the dirty   42 in the boxes. Trying to keep up with all the dirty tables, customers leaving and coming in and   43 running all over the house, it was crazy． 44  these elderly women were watching   45 I was working to make sure every table was clean and ready for the next customers.
When they   46  their meals, I took their plates back to the kitchen. They talked to me for a while about school, how I was doing, what   47 I was in and what I planned to do in the future.

People used to tell me that I couldn’t have a career in    54  until I had a degree. I'm now a co-anchor (联合主持人) of a student-produced television 55 . And the best thing is: I'm only 17 years old and I am a senior in high school.
