The heel is down at the foot: I was pretty sure of that, because when Bernie says heel, which he really never has to, I walk along right beside his feet. The head is the head, at the top. So head over heels means what? The head is always over the heels, except in an upside-down situation, for example when a perp by the name of Nuggets Bolliterri tried to escape on us from an upstairs window and ended up dangling head-first in a tangle of tied-together sheets. Leda had just said Malcolm was head over heels. Meaning what? He was tangled in tied-together sheets? I couldn’t take it any further.
