Handwriting is one of the most useful skills. A person who has learned to write can put thoughts on paper for others to read. Handwriting plays a vital part in communication, and is one of the most important ways of keeping ideas ready for use. People can forget. But handwriting helps them remember. They can use pen or pencil to mark down letters, numbers, and other signs. People can move to another town, city, or country, but handwriting lets them "talk" to one another. The art and practice of attractive handwriting is called penmanship, or calligraphy (see Calligraphy088520).
