It may have been about a month after my sister’s reappearance in the kitchen, when Biddy came to us with a small speckled box containing the whole of her worldly effects, and became a blessing to the household. Above all, she was a blessing to Joe, for the dear old fellow was sadly cut up by the constant contemplation of the wreck of his wife.
– Charles Dickens
