What is the difference
Between your time and my time
Asks a father to a son
Mass and energy balance
Replies the son
In a discussion of time
From where comes
The first course I taught, asks the father
Principles of the course you taught haven’t changed
Interpretations have, says the son
Inputs have always been suitably rewarded
Be it in your time, be it in my time
Inputs have changed their meaning over time
Expectation of one from the other is losing shine
The modus operandi has changed
Minimization of loss is still the operating principle of
Mass and energy balance
Tells the son to a proud father
