Braille is a form of writting used for the extrememly visually impaired and the blind. I am the first. I use braille all the time. People constantly say "damn that's hard" Its not. In case any of you kids at school get a blind/visually impaired kids at your school, don't go crazy when you see braille. I'll show you how to write it but reading it would recquire hands-on study. So here's a description of the letters.

I'll describe braille to those who haven't seen it. It is a series of dots. It looks fonfusing but its not. That's about it.

I should also tell you that in braille there are also contractions. Some examples are:

word braille contraction

also AL
knowledge K

Understand? In case you didn't get what I wrote above about dots here's a basic description of a braille writter.

I don't have a picture of a braille writter so I just a drew one, but this will give you an idea of its basic design.
