There are lots of phrases to describe being crazy, but going bananas seems to be an apt metaphor. Everything seems to be safely encased in the tough, smooth, attractive skin, but then something changes, and your outer skin becomes thinner, more easily bruised, and your insides turn to gelatinous mush. Your inner fruit is no longer nutritive fuel, it’s useless instead. And god forbid you drop the banana on the floor– the greasy and sugary stains and splatters take so much longer to clean than other kinds of messes.
(I am actually feeling much better, I just had this thought while I was editing my flickr stream and cleaning up other assorted greasy-peel messes.)
