Silence
but cover it...Tap your toe, Pick at your jeans, Play around- forums, Text random people, Hum random tunes, Bite your lip, Play with the keyboard- trying to think of what to write- you want to, but what about? Listen to music- like always- breathe deep, calming yourself, Yawn- but cover it, Gasp- hold your sides- but cover it. Everything ends in silence.
