When my younger daughter was in junior school a close friend lived with her mother, sister and the deputy female head of the same school, they rented a two bed roomed house in the town. When the girls were in the high school my daughter said Jenny is moving to one of the big houses which has just been built, she went to the new house, came home said how lovely the house was, Jenny and her sister had a bedroom each , their mother and the deputy head were still sharing a bedroom , i expect they are keeping the fourth for visitors. So sweet. When she was a little older she realised the woman were a couple, no problem. No LGBT history lessons needed
