three o'clock
`` If people should come in here with ever so many pumpkins and candles inside , these blind children would n't know it ; they could n't be frightened . I wonder where they ever heard of ghosts . There must have been some naughty girl here , like Angeline . '' At three o'clock the little blind girls all went out to play in one yard , and the little blind boys in the other . `` Goin ' out to take their air , '' said Katie . Then she and Dotty followed the girls in respectful silence . Almost every one had a particular friend ; and it was wonderful to see how certain any two friends were to find one another by the sense of feeling , and walk off together , arm in arm .
