I used to be a mortgage broker(贷款中间人) in the Phoenix area. In April 2007, the company that I had been with for a year went out of business. That was the latest of the four companies that I had worked for since 2000 .They all either went under or let most of the employees go, including me.

In December 2007, the bank took back my house, and I had no choice but to move in with my parents, five miles away. My sister has three children, and she had no room. My fiancée(未婚妻), Brandi Wetch, and I have been living in my parents’ house for about a year and a half now.

My mother, Sue, works part-time at a high school library. My father left for a job in the Marshall Islands a few months ago and will be gone for two years.

I’m trying to be patient with finding a new job, but it’s been hard. I check the Internet for jobs every morning. I have sent countless letters but have never got a job. I have no idea how many other people are applying for the same job.

I do the housework and washing, and I take care of the garden. Sometimes, I feel like the best part of my life is over. The worst part of the day is when I chat with my friends on the Internet. I’ve talked to about 10 old friends online. The first thing they usually ask is what I’m doing now.

My mother, who is in her 60s, has been so patient and supportive. She acts like she’s happy to have us, not like we’re crowding her. We have learned what’s important since I lived here.
