As the pendulum swings

Not so long ago, I was in Class 9/10. In Hindi class, Sir mentioned the name Bachchan, and then said, "humare waale, aapke waale nahi" clarifying that he is talking about Harivansh Rai, and not Amitabh.

If the exact scene is repeated in a school today, the Bachchans would be Amitabh and Abhishek. Time really flies. Also the generation jump is quantum, not continuous.
