JD comes and goes like the tide in her life — not quite an emptiness, not quite a shore. He carries a clipboard and a smell of diesel, tracks of practical things: permits, measurements, who said what at the town meeting. He talks of mitigation banks and contour lines, of deadlines like nails hammered into the future. Sometimes they argue in low voices over coffee gone cold; sometimes they stand together and watch a heron cut the air and let the world explain itself to them. When he watches her when she works, his eyes are catalogues of admiration and regret, a ledger that does not balance.
