In different periods of my life, the feeling about time were different. When I trace back my high school life, it gave me a special feeling that I spent not three years but 30 years during that period. This reminds me one of my Physics teachers who explained the theory of relativity with an interesting example,which was that if you got along with your boyfriend for a day, you would think that you just spent one hour with him, if you put your hand over a fire for ten seconds, you might feel that it was ten hours. It sounded fun! So, a busy and boring life can make you feel that time becomes longer than usual. Let's get back the topic of weekends. This is Monday, I was a little bit tired of getting up in the morning. I even couldn't remember what I did on the last weekend. A busier schedule than week days made the time went really fast, which also makes the time of Monday to be very slow. Especially when I expect the next weekend , the time becomes slower. I think that only Einstein could manage the time well, other people are controlled by time. I hope that a weekend can be last longer, but I also want to have more fun on a weekend. I can't get both of them at the same time, because I live in a 3-D world, everything has two sides!
