A tiny call-and-response between a stranger and a milkmaid, over almost before it starts. Its back-and-forth pattern makes it a natural for two voices.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
"Little maid, pretty maid, whither goest thou?"
"Down in the forest to milk my cow."
"Shall I go with thee?" "No, not now;
When I send for thee, then come thou."
