Maskenitsa

Since long ago there is a tradition in Russia to say “goodbye” to winter and “hello” to spring. The holiday of seeing off of the winter is called Maslenitsa. The concert is held in our city on this matter, the artists sing age-old songs, chastushkas and organize practical jokes. People take part in different competitions, ride horses and drink hot tea with pancakes not to be frozen. The pancakes are the main attribute of this festival because a pancake is a symbol of the sun. The festival always ends in burning of a big man of straw. The Lenten fast begins after Maslenitsa for orthodox believers. On Forgiveness Sunday in the morning my whole family goes on a visit to my grandmother. She bakes the most delicious pancakes with different fillings. In the afternoon I meet with friends and we go to the central square and see street festivities. I consider that this festival brings people together and let them enjoy themselves and meet the spring together.
