Well, as for me, I have to admit, that I am  very slow person. I do everything really slow. My parents usually make fun of that and call me a snail. That is why time is really my enemy. I am always late for school. And it doesn't matter what time I get up. Once I have almost missed the plane! My parents even had to call the airport to tell that I was late for the registration. I don't know how to do everything faster. But there is definitely one plus - I am the best student in my yoga class! Everything there should be done carefully and slowly. I am sure, in future I will be a yoga instructor, if I am not late for the exam!!
Что касается меня, я должна признаться, что я очень медлительная. Я все делаю медленно. Родители меня обычно дразнят и называют улиткой. В виду этого, время точно мой враг. Я всегда опаздываю в школу. И неважно в какое время я встаю. Однажды я даже чуть не опаздала на самолет. Родители звонили в аэропорт, чтобы предупредить, что я опаздываю на регистрацию. Не знаю как всё делать быстрее. Но определенно есть один плюс - я лучший ученик на занятиях йогой. Все на этих занятиях надо выполнять внимательно и медленно. Уверена, что в будущем я стану инструктором по йоге, если не опоздаю на экзамен
