Day of The Swallows By Estela Portillo
Glossary: lice — мереживо; orb — КРОНА; pail — відро.

Josefa's sitting room is an unusually beautiful room, very feminine and done in good taste. The profusion of lace everywhere gives the room a delicate, ephemeral appearance. The lace pieces are lovely: needlepoint, hairpin, lim¬erick, the work of patience and love. Upstage left is a large bay window; from it, one can view a large tree with a birdhouse of unusual size and shape, an orb that can accommodate a great number of birds. The room faces south, so it is flooded with light. There is almost a melting of light into lace, a peaceful seren¬ity. To the right is a door leading to the kitchen; there is another door leading to a bedroom. Downstage left is a door leading to the outside.
When the curtain irises, Alysea is sitting on the floor. It is before dawn, but a minute or so after the curtain rises, light begins to fill the room. Alysea is clean¬ing the sitting room carpet, an unusual task for this hour. Next to her is a pail. She uses a piece of cloth with quick frantic movements, rinses, and continues the rubbing of the carpet. After a while, she looks at the cloth in her hand almost in a trance, then with a growing horror. She drops it, raising herself to her knees; she stares at it, and then covers her face with her hands. She sits back on the floor leaning her head against a chair, looking helpless and lost. She is sobbing quietly. After a while, she stares at the new streaming light from the window, feeling its warmth as a comfort. The sound of a milk bell interrupts the silence. When she hears it, she jumps up, looks desperately about the room, wipes the traces of tears from her eyes and goes to the window and looks out.
