My left hand won't hold a cup of tea. It is shaking like a proverbial leaf. Is it fatigue-induced shakiness left over from the quite bizarre night I had, or is it because of the very-heavy-and-lethal tomato slicer I carried through town earlier this morning, possibly with that same hand? (I almost wish someone had threatened to attack me, for then I could look lofty and scornful and say threateningly but without making any effort to appear so - "I have a tomato slicer, and I'm not afraid to use it".)
