How to tell that I'm exhausted...

[hufflepest]

I looked down and my iPod and pouted - why was there silence? I thought this track ran all the way to the end. But I skipped ahead anyway.

Silence again.

I pushed up the volume.

Silence.

I sat for a moment in confusion, utterly perplexed. Then it hit me.

...

I'd paused it.

Is it nap time yet?
