### Famous quotes containing the word shape:

“It is as real

as splinters stuck in your ear. The noise we steal

is half a bell. And outside cars whisk by on the suburban street

and are there and are true.

What else is this, this intricate *shape* of air?

calling me, calling you.”

—Anne Sexton (1928–1974)
