It was July 16, 2008 and I was at City Hall to do something thatwould change my life forever. I went to Room 302 and got my workingcard. I thought I was independent and ready to get a job.

First I filled in applications. I put in over 100 applications at restau-rants, clothing stores, and hotels. I kept looking for a job, and I decidedto go to the mall. I was interested in getting a place in one restaurantbecause my good school friend worked there, and he told me they neededpeople. I thought it might turn out to be successful.

One day, when I came home and turned on the answering machine,there was a message on it. It was a job! A lady from a supermarket calledme for an interview on Tuesday. I was very excited. This was my first interview. On Sunday I got up early, my mom and I went shopping fora dress.
