Tick. Tick. Tick.
This is the sound of your life running out.

Unlike clocks, hours have no reverse motion..

Clocks were invented to warn us. Tick (time is passing). Tock (time has passed).

Understanding what makes you 'tick' isn't half as much fun as finding out what makes you 'tock'!

You know, the clock continues to tick. The negotiators, I think, have left things perilously late in light of the date of the summit, which was announced well in advance.

It's a whole team of people working 24 hours around the clock to make me look like this.
