about twelve o'clock
`` But I am going to have a nice time , '' said Jack , looking rather puzzled ; `` I 've got that nice book Winifred brought , and mother 's going to play for me . I wonder what being jealous really does feel like . '' `` It does n't feel nice , '' said Betty , blushing , `` but I do n't believe you 'll ever know anything about it , you 're too dear . '' It was about twelve o'clock when the two little girls , accompanied by Mrs. Hamilton , left the apartment house , and started on their walk across the park , to the Bells ' home on Madison Avenue . It was a beautiful day , and the park was full of children , all making the most of their Saturday holiday . They met several May parties , and Betty told them how her mother had once read them Tennyson 's `` May Queen , '' and how Jack had been so much interested in the poem that he had learned it by heart . `` Jack is really a very clever boy , '' said Winifred admiringly .
