Crunchy heart

I got a bittersweet letter today, containing a poem. A friend of mine invented a phrase for bittersweet: crunchy heart. I love it, it's almost onomatopoeic. A Japanese man, with almost perfect English, expressed his regret at leaving Oxford and going back to Tokyo: 'it was such a perfect trip, the leaving is somehow sweet and sour.'

The poem is a short one -

Divorce

Woke up suddenly thinking I heard crying.
Rushed through the dark house.
Stopped, remembering. Stood looking
out at bright moonlight on concrete.

Jack Gilbert.

Those two words are so perfect: Stopped, remembering. You can feel time standing still. Sweet and sour.
