W.H.Auden, a warning to others to keep their social distance

"Some thirty inches from my nose
The frontier of my Person goes,
And all the untilled air between
Is private pagus or demesne.
Stranger, unless with bedroom eyes
I beckon you to fraternize,
Beware of rudely crossing it:
I have no gun, but I can spit.”

From "About the House" (1966).
