Mother hands me the grocery list and puts money in my pocket, hoping it will be enough. Shes had a hard day, and Ive had a hard week. Nothing out of the ordinary happens when I get to the store. I grab the bread, some milk, and other things on the list. As I turn to head out, I see a beautiful dress in the window. I turn away, bitter that I could never own such a dress.Outside, I cannot stop thinking about that pretty dress. Its not fair that I can never have what I want. I work so hard to help my family and yet I get nothing in return, just another list to do. In my anger, I fail to realize the apples are rolling across the road. Suddenly, I see a pair of hands, offering me an apple. Looking up, I see the tanned （晒黑的 ） face of this stranger. His clothes are mismatched, borrowed or stolen. But his eyes are soft and kind.“ Thanks,I ”say. No other words are spoken as he continues to help me. I tell him “ thankyou”one more time and am on my way because I have many other things to finish. Suddenly, he says, “ Havea good day, maam. ”And then he gives me the biggest smile I have ever seen. Right then, he looks years younger and I feel a fool.Look at me, feeling sorry for myself because I dont get what I want! Do I not think others are in the same boat, or worse? There are worse things than not having a beautiful dress.My mother will hand me the list today. I will make the same journey and probably see something I want but cannot have. But before I start to feel sorry for myself, I will remember the kind stranger with the big smile, and I will grab the last item, and check out.21.
