Real life incident ...
On the way by road to Pune from Mumbai (Bombay), my daughter who was then about 8 years old asked me. (On passing a batch of monkeys seated on the cliffy road parapet)
"Dadda, how many years to go before these monkeys will turn into humans?".
When I recovered, I answered. "Don't know about that, sweetheart! But there's a growing number of humans turning into monkeys."
