Time

Love it... hate it... some value it... others don't... time passes quickly when you're having fun... it is painfully slow when you're bored... we can manage it but can't control it. If it doesn't move forward, we would be stuck in a moment forever. There would be no concept of the past, present or future without it. Time is the perfect oxymoron.
Btw, this was taken while waiting for the train at Raffles Place this morning though I was supposed to be in the office by 8 ;p
