I’m much sorry that I can’t go back home for Mother’s Day next week. This is why I have to go to an important meeting for my boss, who helps me a lot my work and life here. But I’ll find time to seeing you soon. Mom, thank you for which you have done for Tim and me. After Dad died ten year ago, you had to work in a supermarket in the daytime and in a restaurant at the night. Though you don’t have to work now, I can still remember when you came home, you always felt tiring. Tim said he will look for a job near our home. I’m glad you won’t live by myself any more in the future.
