Помогите составить текст на русском  Liked my birthday party! We all had fun. My family gave me lots of presents.I got a new book,Hedgehog Fairy Tales from Father,a little rucksack from Mother,a big white trainer from my brothers and a toy mobile phone from my grandfather.Granny baked a big birthday cake,and Mother put beautiful candles on it.We all had party hats,and they sang Happy Birthday to you!My brothers met Tom. I was so happy about that. They liked him. We danced and played football. Tom gave us an apple and we took it home. But Father wasnt happy. In fact,he was angry. He says people are dangerous. He says that in the daytime i must be with my family and sleep,but i think sleeping is boring.
