Someone asks me what on the earth happiness means? I can’t give you the exactly definition of it, but I’m sure if you love and help others, you’ll get it.
I’ll never forget an old lady. She lives a small house alone. It’s said that her husband and her son were died in a traffic accident. How bitter her life is! But the old lady often helped others with a smile. Wherever it snows, she is always the first to clean the paths. She looks after several children living nearby. I am one of those. I often remember the stories she told about us and her kind smile. Perhaps she is lucky, but I think she is a happy person. Her life full of laughter and love.
