Afsos ke log doodh se bhee jal jaate haiN

Film : Paakeezah
Year of release : 1972
Spoken by : Salim Ahmed Khan (Raaj Kumar)
Spoken to : Hakim saahab (Sapru)

Paakeezah is another film where the writing has what we call 'nafaasat' - a kind of finesse which is very rare in Hindi films. Salim is in front of his family patriarch who has objected to his bringing Saahib Jaan (Meena Kumari) home without determining her pedigree. He has had a similar experience with Shahabuddin (Ashok Kumar) who had, many years ago, brought a woman called Nargis (Meena Kumari again) home. So he says

"Jo log doodh se jal jaate haiN, wo chhaachh bhee phoonk phoonk kar peete haiN"
"जो लोग दूध से जल जाते हैं, वो छाछ भी फूंक फूंक कर पीते हैं"

A visibly irritated Salim retorts with this great line

"Afsos ke log doodh se bhee jal jaate haiN"
"अफ़सोस के लोग दूध से भी जल जाते हैं"

He is referring to the benign nature of milk and using it to hit back at his grandfather's proverb.

This Hindi equivalent of 'once bitten twice shy" is oft used by people. So if it is used in a situation where you disagree, go ahead and say

"अफ़सोस के लोग दूध से भी जल जाते हैं"
