[ JM: The words Shade uses are "bimanist"
not "ambidextrous" (the latter implies a kind of "dexterity" that he
fussily lacks!).]
PS: Shade might have been playing with
the word "humanist," too, when he chose to describe himself as a
"bimanist."
This adds a lot of sparkles to the game, if sound and not
etymological sense prevails, to replace "man" (human, created from
humus) and "manus" (hand).
Perhaps with an additional serendipity: "hum"
(uno, one) and "bi" (two)
