For 52 years my father got up every morning at 5:30 am, except Sunday, and went to work. He returned home at 5:30 pm, for dinner at 6:00 pm. I never remember my father having a night out with his children. All he asked from me as a daughter was to hold his hammer while he repaired something, just so we could have some time to talk to each other.

For 22 years, after I left home for college, my father called me every Sunday. Nine years ago, my father, 67 years old, spent three days painting my house. He asked me to hold the paint brush for him and talk to him. But I was too busy and I could not take the time to hold the paint brush, or talk to my father.

Five years ago, my father spent five hours making a swing(秋千)for my daughter. Again, all he asked me to do was to give him a glass of tea, and talk to him. But again, I had some clothes to wash, and the house to clean.

On January 16, 1996, my father telephoned me as usual, this time from my sister’s home in Florida. I had to get to church, and I cut the conversation short.

The call came at 4:40 pm. That day, my father was in hospital in Florida. I got on an airplane immediately, and on the way, I made up my mind that when I arrived, I would make up for the lost time, and have a nice long talk with him.

I arrived in Florida at 1:00 am, but my father had passed away at 9:12 pm. This time it was he who did not have time to talk, or time to wait for me.
