2.1

The number '1' shows where I live. I live in the first floor. So, I don't have to go up many stairs( we don't have an elevator in my apartment!!) and when I forgot to bring something, my family can hand it to me through the windows. But at night, I have to be worried about thieves a little, and people can see what I am doing in my house through the windows. But as convenience is bigger than bad points, I love my house.
