Sleeping place

　　I don't want to get out for bedclothes because it's freezing recently. I went to bed of top. My bed has top and down. My house is freezing while winter, so it's colder than outside. I'm hard to sit up and don't feel warm. Though I had come in the bed!
　　Mother said," You probably went to bed without your body warmed. "Her words must be right. She continued to say, "You had better sleep in futon because your sleeping place is cold." Thereafter she carpets the futon and gave blanket. This morning, I could comfortable get up. But for she advised me, I would destroy my body.
