Проверьте пожалуйста и исправьте грамматические ошибки.Two years ago my brothers and I were in Almaty without parents. It was one of the best holidays of my life. First, we decided to visit there our favorite rink Medeo but because of repair, we do not agree to stay there. Then we decided to have lunch at restaurant. Tam were all adults and looked at us. After we ate we brought the bill to 29600 tg. We wondered whether we are for so much eaten. Come up with various plans out. But then it turned out that it was not our bill, it mixed up. Sighing quietly, we decided to go to the Fantasy World Aya. It was certainly fun, but we lost it to each other. All were found , except for younger brother, we did not know what to do. We called him all the time and I accidentally discovered that his phone in my bag. We split, looked everywhere. We have considered each carousel, each bench. Night fell, we still could not find him. Suddenly the guard said that there was a boy, we all ran after him. We were shown a very different boy. We have considered each carousel, each bench. Night fell, we still have not found. My brother said that we would return home and tell their parents in extreme cases the police. Upon returning home, we found him there, he quietly played in the computer. We were surprised that he has found a home and we are very happy. It was one of the most adventurous days of my life.
