T.S. Eliot, Old Possum's Book of Practical Cats
“With Cats, some say, one rule is true:
Don’t speak till you are spoken to.
Myself, I do not hold with that —
I say, you should ad-dress a Cat.
But always keep in mind that he
I bow, and taking off my hat,
Ad-dress him in this form: O Cat!
But if he is the Cat next door,
Whom I have often met before
(He comes to see me in my flat)
I greet him with an oopsa Cat!
I think I've heard them call him James —
But we've not got so far as names.”
