First you construct high walls, then you make small windows. And then you keep the curtains closed. I can’t tell you how many times I have walked into the cold air conditioned hospital rooms and found the curtains closed. Is it heat of the day, is it privacy, or is it some other reason? No matter, it’s absolutely standard to have high walls around any private compound or house. In fact they build the walls before they build the house. And, that’s a whole lot of cinder block and expense. Remember with Google Earth, I can look down on you.
