When me was eight years old I was short heigt. Iwas usually clean and quiet, but my sister sometimes was a noisy child.  Our school wasn't new and the clsssroom  was always very cold, but  I was happy at ma first  it.  I was good in maths and russian, but wasn't good sport. My teaches were very good.  My favourite games was the ball. My favourite books were  tales and verses. My favourite food were pasta, fish and egss. My best friends was  Valya Zvereva.
