Dear friend!
I want to tell you about the carnival holiday. This is my favorite holiday. Because on this day the harsh winter ends and a beautiful spring comes. On holiday, we all play together, sing songs, eat pancakes and burn a scarecrow. I invite you to us on a holiday that will take place in late February - early March. Write as you can.
I'll wait for the answer.
