Reassurance rests on the tendon
joining humerus to ulna and brother radius,
a plain broad enough to set up
cup and saucer in the correct contortion—
—If I choose so to bend—
but solid just in imagination taking off
from the solid surface and support under skin
only a clasp of thumb and forefinger,
seconds tensed needed,
even when astride the irregular earth
sharp to any fall
