【题目】

Father seemed to have no hobbies but just took care of his family.

Since I left home for college, my father called me every Sunday at 9:00 a.m.

He was always interested in my life--how my family was doing. The calls even came when he and my mother were in Australia, England or Florida.

Nine years ago I bought my first house. My lather, 67 years old, spent three days painting my house, eight hours a day. All lie asked was a glass of iced tea, and that I hold a paintbrush for him and talk to him. But I was too busy with work to take the time to hold the paintbrush, or talk to my father.

Five years ago, my 71-year-old father spent five hours putting together a swing set (秋千) for my daughter. Again, all he asked was that I get him a glass of iced tea, and talk to him. But again, I had other jobs to do.

On the Sunday morning, 16 January 1995, my father telephoned me as usual. This time seemed forgetful. I had to get to church, and I cut the conversation short.

The call came at 4:40 a.m. which said father was sent to hospital in Florida. I got on a plane immediately. I vowed(发誓)that when I arrived, I would make up for the lost time, for I owed(欠)him a nice long talk.

I arrived in Florida at 6:00 a.m., but my father had passed away hours before. This time he did not have time to talk, or time to wait for me.
