St Valentine’s Day comes on February 14. It is not a national holiday. It is celebrated among people of all ages by exchange of “valentines”. A “valentine” may mean a special greeting-card or a little present. St Valentine is the patron of sweethearts. February 14 is the anniversary of his death. Flowers and candy are favourite presents which sweethearts send to each other. Candy is packed in red heart-shaped boxes and sold for this only one day.
There is a postbox in our school and every year I receive several valentines from boys. I’m not upset, because I know that’s not love it’s just sympathy.
I love this holiday because it gives people happiness and joy. For sweethearts this holiday is another reason to show their love.
День Святого Валентина приходится на 14 февраля. Это не государственный праздник. Он отмечается среди людей всех возрастов, путем обмена "валентинками". Валентинка означает специальную открытку или маленький подарок. Святой Валентин является покровителем влюбленных. 14 февраля годовщина его смерти. Цветы и конфеты являются любимыми подарками, которые влюбленные посылают друг другу. Конфеты упаковывают в красную коробку в форме сердца и продаются только один день.
У нас в школе стоит почтовый ящик, и каждый год в этот день мне приходят несколько валентинок от мальчиков. Но никто не пишет свои имена, поэтому я не могу узнать, кому я нравлюсь.
Я люблю этот праздник, за то, что он дарит людям много радости и счастья. А влюбленным еще один повод проявить свою любовь.
