Good manners are necessary to succeed in business and social situations. As we grow, we become more and more polite.

In the work place, good manners can make the difference between getting job and staying unemployed. When calling to set up an interview, one should be polite and professional to the person answering the phone. Arriving at the interview on time, properly dressed, is another way to impress the boss. Several days after the interview, it is polite to send a letter thanking the interviewer for his or her time. Having good manners like these can increase one's chances of success in the work place. Bad manners are the opposite of good manners.

Deaf people—people who can't hear—are still able to communicate quite well, with a special language. It's called sign language. The speaker of sign language uses hand gestures in order to communicate. Basic sign language has been used for long, long time. But sign language wasn't really developed until about 250 years ago. In the middle of the 1700s, a Frenchman named Epee developed sign language. Epee was able to speak and hear, but he worked during most of his life as a teacher of deaf people in France. Epee developed a large number of words for sign language. Epee's system used mostly "picture-image" signs. We call them picture-image signs because the signs create a picture.
