Возникла потребность в уточнении. Написать короткое письмо другу о том, что вы и ваша семья делаете сегодня дома ( 50-60 слов ) .

Today I'm going to stay with my family at home. We celebrate grandmother's anniversary today. She is 70. We are going to cook lunch, meet other guests and give her presents. I prepeared for my grandmother's birthday beautiful picture. I've made it myself. After the lunch I'll help my mum to wash the dishes. Then we will play the piano, sing songs and play different games with my sister and cousins. In the evening we are going to watch movie.
