Symbols

Mankind invented symbols just
to cut a message down and short.
For the recipient it must
give instantaneous report.

Common knowledge is expected,
otherwise misunderstanding
spoils the message thus infected
and endangers where it’s ending.

Short messages in our days
use an emoticon or letter.
And you must know the role it plays
in understanding even better.

An extensive talk between
two or more is seldom seen.
