Yesterday I think of a friend who had been ill recent. So I sent her a text message to comfort for her. In the evening, her mother, strict teacher, called me. My first thought was that she was going to give me a hard time for send her daughter the text message. With my surprise, her mother thanked me for that I had done. She said her daughter was in low spirit because of her illness and that my text message had cheered his daughter up. It was at that moment that I realized the important of a simple text message.
