One night as I went to the supermarket to buy some groceries（日用品）, something unusual happened to me. It made me review the meaning of life.
As soon as I went through the glass doors, I could tell something unusual was happening at the cash register（收银台）. I saw a cashier taking a few items （物品）out of a customer's bag. The shopper was an old woman. I couldn't even begin to describe to you how sad this woman looked. I stood there for a second and quickly realized that the cashier was taking items off the bill to cut down the payment.
I walked quickly over to the cash register, pointed to the items that she was about to put behind her and then pointed at my bag, showing that I would pay for them. She understood. After putting those items back in the bag at the register, she again went to help the woman with her card, but it still didn't work. I looked at the screen to see the number, took some cash out of my bag, handed it to the cashier and then quickly walked away.
The old woman was a bit nervous about her card and didn't notice me at all. When the cashier told her that she didn't have to pay a cent, she was confused（茫然的）.
I didn't walk back into the supermarket, but I felt so proud. I was really happy that I was able to help the old woman out and hopefully bring some joy and happiness into her life.
What is happiness?As you can imagine, there are a lot of answers. Some people say that giving is a kind of happiness; it gives people warmth and joy. Some people say that harvest is a kind of happiness; it makes you realize the joy and excitement after the harvest. But I think to help others is a kind of happiness. It is the most valuable experience and it will always warm your heart.
