This happened several years ago when I was still quite new in the city. I was doing my grocery shopping one day, and when I wanted to pay for my things, it turned out that I didn't have enough funds on my bank account for the things I’d chosen. It seemed something had been paid from my account that I had forgotten about.

I was so embarrassed and ashamed. There was a queue forming behind me. I became very flustered（慌乱的）and very close to tears. I tried to quickly pick some things out that weren’t so urgent for me to buy. The cashier（收银员）, a patient, elderly man, saw how upset I was and gently said, “Please, don't worry about picking out groceries to leave behind and you can pay me back for the difference another day.” I immediately refused since I didn't know him, but he insisted he would pay for the difference because he also had daughters and sometimes life could be hard. I thanked him greatly while I packed my things. I asked him what his name was so I could bring the money another day. He said, “Just ask for Baba（Father）and everyone calls me that here.”

I came back a few days later with the money, a thank-you card, and some homemade cookies. I asked a young salesman if he'd seen the old man and he immediately told me, “Oh! That must be Baba!” It was clear that he was very familiar with him. I explained what had happened and he nodded. "Yes, that is something he would do. He is a bit of an extra father to all of us working here, too. He isn't working today but I will make sure he gets this."

Thank you, Baba, for looking out for me that day, and for taking good care of your coworkers, too! I think it is people like Baba that make the world beautiful.

Father's Day is celebrated today in 75 countries around the world. In my personal world, it's a day I like to think of my father's father.

I learned a lot in my later life from my dad. But I learned something else, as a kid not even yet in school, from my grandfather. I learned to be curious. Little things fathers and grandfathers do can change the life of a child forever. In my case, this change came from necessity: My mom needed someone to look after little Allen, barely 4 years old, during the school day. My grandmother volunteered, and my grandfather came up with a way I could be watched while he worked in his clockmaker's shop.

He seated me on a chair every day while I was there, right in front of his big workbench. He told me stories. He had a great sense of humor and a funny way of making a "buh-buh-buh" sound when he sensed my attention was weakening, and he encouraged me to ask questions about anything he was doing.

Naturally, I was usually asking questions about clocks--what made the hands move, what the pendulum(钟摆) did, why you had to stop winding just before the weight hit the stop. Sometimes I just asked about which shiny parts went where.

Most of all, he showed me how clocks worked. He treated me as if I were a sort of small grown-up. He never talked down to me, never told me I was "too young to understand".

And so my grandfather granted me two things: A love of clocks, and an everlasting curiosity.

As a journalist, I turned that fascination into explanations of why computers and software do what they do——and, perhaps even more importantly, why they fail at that task. I haven't been afraid of opening up the innards and looking for what is wrong with the computer.

Once, Buddha was walking from one town to another with some of his followers. This was in the initial days. While they were traveling, they happened to pass a lake. They stopped there and Buddha told one of his followers, “I am thirsty. Please get me some water from that lake there”.

The follower walked up to the lake. When he reached it, he noticed that some people were washing clothes in the water and, right at that moment, a bullock cart started crossing the lake right at the edge of it. As a result, the water became very muddy, very dirty. The follower thought, “How can I give this muddy water to Buddha to drink?!” So he came back and told the Buddha, “The water in there is very muddy. I don’t think it is fit to drink.”

So, the Buddha said, let us take a little rest here by the tree. After about half an hour, again Buddha asked the same follower to go back to the lake and get him some water to drink. The follower obediently (顺从地) went back to the lake. This time he found that the lake had absolutely clear water in it. The mud had settled down and the water above it looked fit to be had. So he collected some water in a pot and brought it to the Buddha.

The Buddha looked at the water, and then he looked up at the follower and said, “See, you let the water be and the mud settled down on its own. You got clear water. It didn’t require any effort”.

Our mind is also like that. When it is disturbed, just let it be. Give it a little time and it will settle down on its own. You don’t have to put in any effort to calm it down. We can judge and best decisions of our life when we stay calm.
