“Must: initiates a compulsion
have to do is forceful
a rule rather in the run
could not escape or slip in excuses
must do is a rigorous discipline
follow it up with a vigour
you have to rather
a discipline plays the role
never you could look for a loophole
like it or not you have to do
that be the “must” in all
ascribe anything more
could land on nothing more
well, that is the nature of the word
a strict adherence to the detail
an uncanny attitude to the minute
the “must” comes with a bang
dare to evade it at any time
have to face dire consequences
cases could lead to a punishment
might put you in imprisonment
deviation would lead to problems serious
beware of the word “must” at all times
follow it with no distraction every time 
you would enamour all with a chime
