a good memory of student life Hi,This is a sweet memory when i was student in bachelor of science in Qazvin. We were five boys who had rented a large house. We had a landlord who was old man and very kind. One night in winter, It was snowing and very cold. I usually wear light clothes. One of my friends and I had slept on one of a room. At midnight, I felt my body who is hot, So I got up and open the window and then went back to bed. After several minute I woke up again and I found it that windows was closed.For second time, I got up and opened the window. When I was going back to bed,my friend said me :"Why do you open the window,It's cold". I said him:"I'm hot and I can't sleep. Please use one more blanket and Don't close the window". He didn't accept it and we had a funny challenge for opening and closing window. At finally, I got up and separated window from hinges and put it at commode :D . My friend had been thinking for several minutes and then I sea him who separated Door of the room from hinges and put it front of the window :D. Whenever I remember That night ,It's sweet.
