Chapter Twenty Getting to Know the Rivers Family I stayed one month at Moor House. In that time,I came to love the little house,and the wild,beautiful fields around it,just like Diana and Mary did. We read books together and talked about them. Diana began to teach me the German language,and I helped Mary with her drawing. We were very much alike,so we spent the days and nights very happily together. But St.John hardly ever spent time with us. He was usually visiting poor and sick people in a little village called Morton,near to our house. Even if the rain fell and the wind blew,he always went there. I did not think St.John was a happy person. Often,I would see him staring out the window with a sad look on his face.
