So we all drove away with three cheers for Mother, and Mother stood and watched us from the verandah for as long as she could see us, and Father waved his hand back to her every few minutes till he hit his hand on the back edge of the car, and then said that he didn't think that Mother could see us any longer.
Well, we had the loveliest day up among the hills that you could possibly imagine, and Father caught such big specimens that he felt sure that Mother couldn't have landed them anyway, if she had been fishing for them, and Will and I fished too, though we didn't get so many as Father, and the two girls met quite a lot of people that they knew as we drove along, and there were some young men friends of theirs that they met along the stream and talked to, and so we all had a splendid time.
It was quite late when we got back, nearly seven o'clock in the evening, but Mother had guessed that we would be late, so she had kept back the dinner so as to have it just nicely ready and hot for us. Only first she had to get towels and soap for Father and clean things for him to put on, because he always gets so messed up with fishing, and that kept Mother busy for a little while, that and helping the girls get ready.
But at last everything was ready, and we sat down to the grandest kind of dinner - roast turkey and all sorts of things like on Xmas Day. Mother had to get up and down a good bit during the meal fetching things back and forward, but at the end Father noticed it and said she simply mustn't do it, that he wanted her to spare herself, and he got up and fetched the walnuts over from the sideboard himself.
The dinner lasted a long while, and was great fun, and when it was over all of us wanted to help clear the things up and wash the dishes, only Mother said that she would really much rather do it, and so we let her, because we wanted just for once to humour her.
It was quite late when it was all over, and when we all kissed Mother before going to bed, she said it had been the most wonderful day in her life, and I think there were tears in her eyes. So we all felt awfully repaid for all that we had done.-
