Today I found time was a cruel thing. Whatever man is, time always goes on.It won't stay to wait for somebody. You can't use anything to exchange time. Time is also a fair thing. Although you have a lot of money or you enjoy high reputation, time won't leave them more. Today I found I hadn't enough time. Although I have 50-day holiday, but I found I had a lot of things to do. I had a lot of homework to do and I had something necessary to do.
