жила была девочка. она была совершенно невоспитанная. она рвала цветы на клумбе,обижала младших, не здоровалась и не хотела учиться в школе. как-то раз ее  мама решила что пора с этим кончать. девочке нравился мальчик из ее класса. его звали илья.  но он не обращал на девочку внимания. и даже сторонился ее. 

все друзья и подруги девочки отвернулись от нее и не хотели с ней общаться. тогда мама объяснила девочке что,чтобы у людей складывалось хорошее впечатление о ней и она имела много друзей,ей надо стать вежливой. с тех пор девочка стала воспитанной и приятным человеком. и все у нее в жизни было хорошо. 

lived a girl. she was quite ill-mannered. she tore up the flowers in the flowerbed, offended the younger, not greeted and did not want to go to school. once her mother decided it was time to finish it. the girl liked the boy in her class. his name was ilya. but he did not pay attention to the girl. and even shunned her.
