`` oh no , my sister , we must launch you into legend and song , '' i said , and i led us clattering into the street behind the school , where the dormitory windows look down but mistress 's windows do not , and i wheeled us about in grand fashion , with the horses ' whinnies and their hooves making a great loud show of it , till i spotted a few faces in the windows and then i bounded down and gave up my hand and helped amy off of hildy .
