The Old Pincushion by Mary Louisa Molesworth

The next two or three days passed most pleasantly. The weather, as if to make up for its bad behaviour on the day of their journey, was particularly fine, and the children were out from morning till night. Old Martha thought privately to herself that it was a good thing the neighbours were so kind, for they were even 'better than their word,' in sending all sorts of good things to Ty-gwyn for the Captain's children, as Neville and Kathleen's appetites, thanks to the change of air and the sea breezes, were really rather alarming. And Miss Clotilda was so perfectly happy to see them both so bright and well, that she tried to banish all painful thoughts as much as she could.

Still they were _there_; and when the poor lady was alone in her room at night, it was often more than she could do to restrain her tears. For the happier the children were, the more she learned to love them, the more bitterly, as was natural, did she feel the disappointment of not being able to hope to see much more of them. But she said little or nothing of her feelings, and the children -- Kathie especially -- little suspected their depth. Kathie was living entirely in the present; she but rarely gave a thought to the ideas Philippa had suggested. And Neville, though less carelessly light-hearted and forgetful, was slower both of thought and speech. He could see nothing to be done, and for some time he rather shrank from coming upon the subject with his aunt.
