In the past, I always thought that time was fixed, eternal and unaffected by other things. But since I was promoted to the grade, I found that the original time also had its ups and downs.

Whenever I finish my homework, I get used to turning on the TV, chasing variety shows and watching animations. My mother only gives me half an hour to one hour at a time, which is far from enough for me. Time is often fleeting, and you will be forced to turn off your phone for a while.

Whenever I went on a trip, when I first got on the train or plane, I felt that the journey in these ten days or so was very long. When I was ready to go back, I found how the travel time passed so quickly!

But there are also many times, the time will become very long.In hip-hop class, the teacher always asks us to practice our physical fitness for an hour. In the course of training, I always feel that time is in trouble, deliberately stretching for a long time, just to let us practice a little longer! When my relatives took my family to dinner, I also felt that it was a long time. They eat time, is chat time, the children have mobile phones to play, my parents do not allow me to touch the phone, I can only silently in a daze, waiting for them to finish eating.

But in any case, time seems to be against all of us, which bothers me.
