Beware if you introduce facts bystanders shall forthwith make tracks

Aren’t words just something we utter
so no cause to get uptight?
As something we just let flutter
no need for feeling contrite?

Take care to avoid some subjects
while be up on latest trends
Lay off our usual suspects
who talk Tesla but drive Benz

Above all don’t appall them all
by acting the rumpled sleuth
who with hapless self-righteous gall
goes out looking for The Truth!

Beware that if we bring up facts
bystanders shall forthwith make tracks!
