Christina is on a two-week vacation.
This is the first vacation she has had for a long time.
The last vacation she took was more than two years ago.
Now she is visiting a friend in San Francisco.
Her friend and her husband are living near the center of the city.
He works for a start-up company in Silicon Valley.
While he is working, she works part-time at a department store.
Christina hasn't seen her friend for a long time.
The last time they saw each other was 3 years ago.
At that time, they were both working at a department store.
Then Christina quit her job and started her own business.
She designs women's clothing.
She has 2 employees now and her company is slowly growing.
Christina has come to San Francisco by herself .
Her husband didn't come because he has to work.
He tried to start a company 2 years ago but it didn't work out.
His company failed after only a few months.
So now he's working at another company and saving money.
Once he saves enough money he plans to start another company.
He doesn't want to give up.
This is the second time Christina has been to San Francisco.
The first time was when she was a high school student.
That was more than 10 years ago.
During that trip she was only in San Francisco for a few days.
After that she went to Los Angeles and New York.
This time she and her friend plan to relax and have fun.
