Poor little girl! What could she do under such trying circumstances--what indeed but go to mother. All the way up the long stairs she went to where mother was as busy as ever a mother could be doing something with a lot of things that were piled all over the room. But mother, when she saw the tear stained little face, understood in a flash and put aside whatever it was that she was doing, quickly, and held the little girl, dolly and all, close in her mother arms until the feeling of being in the way and of not being wanted was all gone. And, when the tears were quite dry, mother said, so gently that it did not hurt, "No dearie, I'm afraid you can't help mother now because mother's girl is too little to understand what it is that mother is doing. But I'll tell you something that you _can_ do. Mother will give you some things from the pantry and you may go over to see the little boy. And I am as sure, as sure can be, that, when he sees all the nice things you have, he will play keeping house with you." So the little girl in the Yesterdays, with her treasures from mother's pantry, went out across the garden and through the hedge to find the boy. Very carefully she went through the opening in the hedge so that she would lose none of her treasures. And oh, the joy of it! The splendid wonder of it! She found that the boy had built a house--all by himself he had built it--with real boards, and had furnished it with tiny chairs and tables made from boxes. Complete it was, even to a beautiful strip of carpet on the floor and a shelf on which to put the dishes. Then, indeed, when the boy told her how he had made the house for her--just for her--and how it was to have been a surprise; and that she had come just in time because if she tad come sooner it would have spoiled the fun--the heart of the little girl overflowed with gladness. And to think that all the time she was feeling so not wanted and in the way the boy was doing _this_ and all for her! Did her mother know? She rather guessed that she did; mothers have such a marvelous way of knowing everything, particularly the nicest things. So the little girl gave the boy all the treasures that she had brought so carefully and they had great fun eating them together; and all the rest of that day they played "keephouse." And this is why that day was among the best of all the woman's Yesterdays. Several men going home from work passed the spot where the young woman sat. Then a group of shop girls followed; then another group and, in turn, two women from an office that did not close early on Saturdays. After them a young girl who looked very tired came walking alone, and then there were more men and women in a seemingly endless procession. And so many girls and women there were in the procession that the woman, as she came back from her Yesterdays, wondered who was left to make homes for the world.
