In Act II, Scene 5, the Nurse returns to Juliet from her visit to Romeo, and while she teases her eager young charge relentlessly, claiming to be too tired and out of breath to tell Juliet what Romeo has said, she clearly approves of Romeo, though not without reservations. She has already registered her preference for Paris, and she even as she claims (somewhat teasingly,) that "you know not how to choose a man," she goes on:
Though his face be better than any man's, yet his leg excels all men's; and for a hand and a foot, and a body, though they be not to be talk'd on, yet they are past compare. He is not the flower of courtesy, but, I'll warrant him, as gentle as a lamb.
Elsewhere she describes him as "honest," "kind," and "virtuous." She is concerned about the decision Juliet is about to make, especially given that she has another, less controversial suitor in Paris, but seems to be resigned to the fact that Juliet is in love, and will do what she wants. In any case, she seems to generally like Romeo.
