My sister is a Feminist

I just told my sister (10) about my fistball team (which consists of women only and in german is called “Mannschaft” = “Manteam”) and her immediate response was:“ Why always “MANNschaft? Why never FRAUschaft (which would be womanteam) ?”.
And when I was like “hey, I like that that angers you” she said “yeah it’s just really unfair! It’s always ‘Arzt’ and never ‘Ärtztin’ (masculine and feminine form of doctor). And also when I read, the man is always the hero! The princess is always saved by a man, why can’t a woman be a hero for once?”

My little sister, all by herself, became a feminist and I am proud.
