only grandmothers can. Polly felt this; and, as she missed the home-petting, gladly showed that she liked to see the quiet old face brighten as she entered the solitary room, where few children came, except the phantoms of little sons and daughters, who, to the motherly heart that loved them, never faded or grew up. Polly wished the children would be kinder to grandma; but it was not for her to tell them so, although it troubled her a good deal, and she could only try to make up for it by being as dutiful and affectionate as if their grandma was her own.
Another thing that disturbed Polly was the want of exercise. To dress up and parade certain streets for an hour every day, to stand talking in doorways, or drive out in a fine carriage, was not the sort of exercise she liked, and Fan would take no other. Indeed, she was so shocked, when Polly, one day, proposed a run down the mall, that her friend never dared suggest such a thing again. At home, Polly ran and rode, coasted and skated, jumped rope and raked hay, worked in her garden and rowed her boat; so no wonder she longed for something more lively than a daily promenade with a flock of giddy girls, who tilted along in high-heeled boots, and costumes which made Polly ashamed to be seen with some of them. So, she used to slip out alone sometimes, when Fanny was absorbed in novels, company, or millinery, and get fine brisk walks round the park, on the unfashionable side, where the babies took their airings; or, she went inside, to watch the boys coasting, and to wish she could coast too, as she did at home. She never went far, and always came back rosy and gay.
