Two varying pictures outside the classroom window

There are two different pictures outside the classroom window, when you sit down your chair or stand near the window. The blue sky and cloud catch in my eyes,which is different form the China that is filled of smog,when sitting.And you are able to see two colors of tree which is red and yellow.And you can see the D angler is in the right side.
However, it is a different picture when you standing near the window.You will see folk walking around.We can see that the building of university career services is in front of us.Interestingly, some peoples will look up at us and say hello to us.After a few minutes ,I notice near the stair that a girl who needs lighter to light her cigarette is asking a man.Naturally,the man help her do it with his lighter.I feel that moment sharing the flame is a kind of powerful and intimate situation. Their hands almost touch, the girl watches the flame and the man stares at girl.That is intense intimate between them.
