DD came back today and her friend came over, they both came back talking about how shocked they were at their (30s male) science teacher.
Apparently they got onto the topic of puberty and the boys were chiming in with the usual stuff about boobs and ageing and the teacher said that it's a scientific fact that a female's prime is at 18 years of age...
I think it's disgusting. Especially when the class already has had problems with sexism (supposedly being tackled) after year 10 joiners have tipped the small class from being 9 boys and 6 girls, to 16 boys and 4 girls.
