None of your business
Nasreddin Hodja

While walking homeward in the evening the Hodja was stopped by a fellow villager known to be an ardent devourer of sweets.
-Hodja, a short while ago I saw a fellow carrying a huge tray of fine desserts...
-It's none of my business!
-But the fellow was taking the tray into your house.
-Then it's none of your business!
