ten o’clock
`` Well , yes I am , '' Betty admitted , dodging under the piano and smiling impishly from this point of vantage . `` Now , Florence , you are selfish , '' she teased ; `` it 's bad enough having no Thanksgiving vacation , but after the way I 've worked my fingers to the bone for you , you should n't , no , you really should n't begrudge me a lemon . '' Florence tried hard not to smile in the face of Betty 's mournful expression , and made an attempt at rescuing the stolen fruit . The above took place at ten o'clock on Thanksgiving morning . The Assembly Hall was filled with busy girls , and it was evident that preparations of some kind were under way . Owing to an epidemic of mumps the girls had been kept in school over the holidays , and for their amusement , and to ward off any chance of the more serious epidemic known as `` homesickness , '' the Seniors had been bidden to entertain . Florence , having unsuccessfully pursued Betty twice around the hall at a rate highly unbecoming a dignified Senior , paused for breath , and Lois , Polly and Angela , who had watched the chase with interest , came to her assistance , and captured the lemon from the now unresisting Betty .
