The windows are a style called 'jalousy windows' which are the worst design known to man. Each window is made many long 4" wide pieces of glass running horizontally and secured at the ends into the mechanism that rotates them open. A pain to clean the glass, the metal parts would corrode, bind, and strip the crank...and no way could a person sneak out through them.
Funny but back then I was really scared of my parents, not so much of the whooping I got now and then but of being so ashamed to do something wrong plus the whole neighborhood would know about it too.
