Call Me Irresponsible

Call me irresponsible - call me unreliable
Throw in undependable too
Do my foolish alibis bore you?
Well I'm not too clever - I just adore you
Call me unpredictable - tell me I'm impractical
Rainbows I'm inclined to pursue
Call me irresponsible - yes I'm unreliable
But it's undeniably true - I'm irresponsibly mad for you
