poem from a bus

"something to desire"

when there's something to desire,
there's something to regret,
when there's something to regret,
there's something recall,
when there's something to recall,
there's something to regret,
when there's something to regret,
there's something to desire

a poem i saw from the metro bus..
quite funny, but come to think of it..simple yet full of meaning! =)
