We could all say that we have bad days as we go through life, but what does it take to have a really good day?

    I remember a day recently when I had to go to the 1 for special tests because I wasn't feeling well and my doctor sent me to a specialist to try and find the cause of my illness.

    As I 2 to the hospital, I was feeling sad and certainly wasn't on top of my game. As I got to the hospital, I began my 3 for a parking lot. I finally found one not too far from the entrance to the hospital.

    As I got out and brought my change out of my pocket, I noticed a man looking a little 4 standing in front of a parking meter (停车记时收费表) two cars away. He seemed to be searching his pockets for what I supposed were 5 for the meter.

    Although I 6 didn't feel that great, I thought that I should at least go over to him and find out if I could 7 him. As I stood beside him, he turned to me looking worried. I asked him if he had a problem I could help with. He said that he had no coins at all because he was only thinking about visiting his sick wife when he left his house.

    I reached into my pocket and 8 out two dollars and gave it to him without saying a word. And, without waiting for a reply, I turned on my heel and said to him as I was walking away: “Have a good day.”

    The funny thing was that I felt a lot brighter, a small smile came to my face, and I seemed to walk just a little quicker. I was walking away when he called out: “Thank you so much.” You know, I didn't even 9 him to say anything. He didn't have to say a word to me. It was simply enough to know that I had helped someone else who needed a little10. That's all it took to bring a smile to my face as I went on toward completing my own business.

    You know, it doesn't take much to help someone else.
