Dear Mom, I'm sorry that I can't go back home for Mother's Day next week. On that day, I'll have to go to an important meeting for my boss, who helps me a lot with my work and life here. But I'll find time to see you at home soon. Mom, thank you for everything you've done for Tim and me. After Dad died of a heart attack at home ten years ago in a road accident, you had to work in a supermarket in the daytime and in a restaurant at night. But you always gave us two your love and care. Though you don't have to work now, I still remember your coming home and feeling tired many evenings. Tim is going to finish his studies next month. He said he would move back from school and look for a job near home. I'm glad you won't live by yourself any more. Let's plan to take a trip in the near future. It's been years since the three of us took a trip together. Happy Mother's Day. I love you, Mom. Best wishes, David What can we learn about David's mother?
She still works day and night. She lives all by herself now. She is making a plan to save money. She used to be too busy to look after her children.
