The mom probably thought the girl could become sexually active at any time, although since the last name sounds Caucasian it is unlikely.
But we have such a large population of black and Hispanics that reach puberty at age eleven or twelve, doctors have probably made a sweeping age recommendation for all races.
Kind of like we had the food pyramid so very high in bread and grains so as to feed those in the population with less resources.
If she is really leftist, she probably hoped the girl would be sexually active. A proud moment for sure.
