the Hopi culture is not the only one that allowed young people to visit each other at night some Bavarian people of southern Germany once had a windowing custom that took place when young women left their windows open at night so that young men could enter their bedrooms when a woman became pregnant the man usually asked her to marry him. but women who did not manage to get pregnant after windowing were often unable to find a husband.This was because fertility was a very important requirement for woman in this culture,and the windowing custom allowed them to prove their fertility to others in the community.Some people are surprised when they learn of this unique custom because they expect the people of southern Germany to follow the rules of the Catholic religion,which teach that it is wrong for unmarried woman to become pregnant.But the windowing custom is only one example of the surprising views of marriage that are found around the would,even among people whose religious beliefs require more common marriages practices
