Ghalib chhuti sharaab par abhi kabhi kabhi
Peetha hoon roz-e-abr-o-shab-e-mahtab mein

Ghalib, the bottle is in my past now, but yet, once in a while
I drink on days that are overcast, and on nights moonlit

[you have to remember that for people from desert climes, an overcast day isn't dreary, but full of the expectation of life-giving rain. see, for example, http://j.mp/ghananghanan]
