[MattK]

A headless man had a letter to write;
It was read by a man who had lost his sight.
The dumb repeated it word for word;
And deaf was he who listened and heard.

Solve this riddle.

It had to be nothing , headless man is dead
The blind could read; unless it was in braille
The person who was dumb could repeat nothing.
A deaf man can not hear so he heard nothing.
