Once at school I had a funny story. We rehearsed, did the dance for the new year and left the portfolios on the benches. Then when we finished we went into the dining room. My friends and I ordered pies. Then I decided to get the money and pay. I see but there is no portfolio! I was very scared. I went to the place where I left the briefcase and it was not there! Then my friends laughed and said that they had a briefcase.
однажды в школе у меня случилась смешная история. Мы репетировали, делали танец к новому году и оставили портфели на скамейках. Потом когда мы закончили мы зашли в столовую. Я и мои подруги заказали пирожки. Потом я решила достать деньги и заплатить. Вижу а нет портфеля! Я очень сильно испугалась. Я пошла к тому месту где я оставила портфель и его там не было! Потом мои подруги рассмеялись и сказали что портфель был у них.
