Do not let anybody tell you the first part is the easy part.

The first part is the only stretch done entirely without evidence.
Everything since has been paid for with proof —
a line in a book, a plate that went on and stayed on.

That first winter was paid for with nothing at all,
by somebody who had no reason yet to believe any of it,
and who went anyway on a night the stairwell light was out.
