Everything
What you do or do not do can affect everything.
Everything.
A whisper, an exclamation, an instant message
If you let one word slip
Or two
You could regret every single word, and those that follow it
Everything.
An apology, a secret, a story
The knowledge of everyone in a matter of seconds
If only you'd made one movement
A finger upon a mouth, a hand off the keyboard, a purse of the lips
And everything would have been okay.
Everything.
