I never thought I would have a life-changing experience at Wal-Mart.

Although my thoughts were only on speed, the checkout line I was standing in wasn’t moving as quickly as I wanted, and I glanced toward the cashier. There stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he’s an old guy!

For the next few minutes I watched him. He greeted every customer before scanning the items. Sure, his words were the usual, “How’s it going?” But he did something different—he actually listened to people. Then he would respond to what they had said and engage them in brief conversation.

I thought it was odd (古怪的). I have grown accustomed to people asking me how I was doing simply out of robotic conversational habit. After a while, you don’t give any thought to the question and just say something back. I could say, “I just found out I have six months to live,” and someone would reply, “Have a great day!”

But that wasn’t the end. He gave them the change, walked around the counter, and extended his right hand in an act of friendship. He looked the customers in the eyes. “I sure want to thank you for shopping here today,” he told them. “You have a great day. Bye-bye.”

The looks on the faces of the customers were priceless. There were smiles and some sheepish grins (咧嘴一笑). All had been touched by his simple gesture—and in a place they never expected. They would gather their things and walk out, smiling.

Of course, he did the same to me and I got to know his name, Marty.

Time is very important in our lives. It organizes our everyday moments. However, time never had any importance in my life until I received a watch from my father.
I received this gift on a cloudy day. I had to go to the airport at 9:00 a.m. to meet my uncle and take him to my father’s house. However, I was late because I was staying with my friends. Later on that day, around 11:00 a.m., I remembered my uncle, but I was very late for him. He had left the airport and taken a taxi to my father’s house.
I got to my father’s house at 2:00 p.m. and felt ashamed of myself at that moment. After I said “hello” to my angry father and tired uncle, my father asked me to sit next to him and gave me this watch. Then he said, “Essa, did you have fun with your friends today?”
“Yes, Dad, and I’m sorry about not meeting my uncle at the airport.”
“I hope today you learned something important, and this watch will be a reminder (提醒物) for you.” He told me to take this watch and use it as an organizer of my life.
I learned a very important lesson from my father: To respect time and never be late to do something. This watch is important to me, not because of its price, but because of the lesson that I learned from it.
