The title is the literal translation of a south Indian proverb, used to describe situations where a person who's already guilty will be proven so, if he voices himself against something.
From the literal saying : A thief entered a house at night, and a scorpion stung him. He cant shout out loud, otherwise he'll be caught. He just has to bear it.
A student skipped school on the day of a field trip to a local hospital, unbeknownst to his parents. The parents later found out that there was a break out of some disease at the said hospital and decide to get him a preventive vaccination for it. He doesn't like injections, but cant tell his parents that he didn't actually visit the hospital.
