A good poem messes with your head. Or should. It sneaks in there, starts grabbing fistfuls of wires, yanking out some, jamming in others, making new connections like the operator at a telephone switchboard. You come away not quite thinking the same as before.
Not every poem for every person, of course. That’s why there are so many poets and so many poems. Even a poet you love can leave you cold. I’ve read T.S. Eliot’s “Four Quartets” again and again. The cat poems? Once is plenty.
