“Do you like my dress?” She asked a lady. “My Mum made it just for me,” she said with tears in her eyes.

“Well, I think it’s very pretty, so tell me, little girl, why are you crying?”

The little girl answered in a low voice, “After Mum made me this dress, she went away. My Dad says that she’s up in heaven with grandfather.”

Finally the woman realized why she was crying. She felt very sorry for the little girl and held the child in her arms.

Just before the lady wanted to go, the girl stopping crying, walked back from the woman, and showed her a spot (点) on her dress, and said, “Right here is where my Mum kissed my dress, and here,” pointing to another spot, “and here is another kiss, and here, and here. Mum said that she had put all those kisses on my dress so that I would forget my sadness.”

The lady realized that she wasn’t just looking at a dress, no, she was looking at mother. The mother knew that she was going away. So she gave all her love to her lovely daughter and put it into the dress.

The lady no longer saw a little girl wearing a simple dress. She saw a child in her mother’s love.
