Just One Word - Two Letters - Single Syllable

.

Communication
Introduction
Informal
Painless

Two letters
A greeting
Simple enough
One syllable
A breath

Never that easy
Nerves tense up
Thoughts are jumbled
One little word
Becomes much more
Many possible mistakes

Can't find the courage
Even to approach you
Fearing initiating a conversation
Knowing how to start
But not finding something
Missing that opening line
Just breathe and speak

Hi.
