A nubile young woman, still a beautiful inchoate creature, malleable and attractive to many older men in her community, was of the age where parents noticed she was still unmarried. Especially their fathers would adduce that fact with other parents of the same age young women. The best goal was to have their daughters married by a certain age.
In other societies it seemed too young. Those parents allowed their daughters to test out their own choice for a lifetime partner. A parents choice would be considered, but the ultimate choice was to step aside to rest until their child decided on her own.
