Usually standing next to the one you already have

One household at a time, computed rather than guessed

The register already knows who is married to whom, whose child sits on whose plan and who introduced whom. This draws it. The layout is computed, not simulated, so it gives you the same picture every morning and you build a memory of where your own people sit. Your clients are ringed; everybody the register knows about and nobody has asked is faded, behind a dotted line.

Where it stopsNobody is sized by what they pay. It counts records and never money, and every route out of it is an introduction rather than a number to dial.
