Be thou familiar, but by no means vulgar.

The lines of vulgarity have stretched rather wide in recent years.
They’re like a waistband on an old pair of pajamas
Stretched so far beyond its old form
As to be unable to return to its smaller shape
The way it used to.
We have drifted from a jolly familiarity to a comfortable vulgarity.
We’d probably have to make a whole new set of pants
To get this waistband back to itself.
