It was autumn. The trees were yellow and red. The hare was grey. He was afraid of winter. In winter snow is white and I\'m grey. The fox can see and eat me. \'\'You should fly away,\'\' - the bird said. \'\'I can\'t fly\". \'\'May I stay with you?\'\' - the hare asked the bear . \"No,\'\' - answered the bear. One day it was snowy. The hare saw a fox but the fox didn\'t see the hare. The snow was white and the hare was white. \'\'I shouldn\'t be afraid of winter and the fox\", - said the hare.
