Say that she rail; why, then I'll tell her plain She sings as sweetly as a nightingale: Say that she frown; I'll say she looks as clear As morning roses newly wash'd with dew: Say she be mute, and will not speak a word; Then I'll commend her volubility, And say she uttereth piercing eloquence: If she do bid me pack, I'll give her thanks, As though she bid me stay by her a week: If she deny to wed, I'll crave the day When I shall ask the banns, and when be married.†
Scene 2.1
