etiquette

My mum taught me,
when I was wee,
the rules to please my gran:
“Get your elbows off the table”
“Say ‘please and thank you’ whenever able
And don’t eat with your hands.”
“To ma’am and sir
One should defer
Yes, even sometimes
When they’re wrong.
With family it’s sometimes best
To go along to get along.”
In company, aim for grace,
Be civil and refined.
One should by the gentility
Of their manners be defined.
The etiquette she taught me
has served me very well,
But if you think it doesn’t...
You can fuck off straight to hell.
