Beware the commuter who sits on the train
The one with the tickly cough
He may have the plague or some avian flu
That’ll probably carry you off.
Put a bag on his head if he doesn’t object
Though try not to cause a kerfuffle
As he may be contagious when flailing about
For lurgy can spread in a scuffle.
Avoid meeting strangers if ever you can
Though of course this can be quite a fuss
Wear a mask if you have one, and try to avoid
Those people who go on the bus.
Your compulsion to travel shows little concern
For your body’s infection defences
Mixing with people endangers your health
Stay home till you come to your senses.
