“The men at the ice house. From she can tell from the times during her first year when still newly wed, she is invited and accompanies her husband sits mute beside their conversation waits and sips her beer until it grows warm, twists a paper napkin into a knot and another into a fan, one into a rose, nods her head, smiles, yawns, politely grins, laughs at the appropriate moments, leans against her husbands sleeves, tugs at his elbows and finally becomes good at predicting where the talk will leads, from this Cleofilas concludes each is nightly trying to find the truth lying at the bottom of the bottle like a gold doubloon on the floor sea” pg1403
