Homes in that time, were simple and really different from ours. Many children in the 1940s lived in small houses or flats. There were blocks of flats too, though they were not as tall as the ones we have today. A typical family house had a sitting room and kitchen, with two or three bedrooms upstairs. The peculiarity of this houses was that that toilet or bathroom not always was inside the house, and not all the houses had one of it. Every window had ‘blackout curtains’, which were drawn at night. They were used to protect the family from being seen by the air forces who threw bombs at night.
