Keeping the window down

Though all the carriage frown,

Why dost thou so rejoice in air?

Not air that nourishes and braces,

Such as one finds in watering-places,

But air to chill a polar bear—

Malignant air at sixty miles an hour

That rakes the carriage fore and aft,

Wherein we cower;

Not air at all, but sheer revengeful draught!
