Everybody's different. Nobody's perfect.If you look around, you'll see kids who don't have good eyes.They have to wear glasses in order to see.Other kids you know break out in a rash when they eat certain foods (this is called allergic), yet others can't hear well, don't talk like everybody else (like those who s-t-u-t-t-e-r), don't learn as fast as other children, are very short or very tall, or very thin, or very, very fat.

Everybody's different.Nobody's perfect.Some kids can't run as fast as others can.Even though they get where they're going, it takes them more time to get there.Their legs are weak, and they have a hard time jumping, running, climbing stairs, or just keeping up when they are playing with other kids.This is called muscle weakness and it's caused by a disease called muscular dystrophy.
