Edit: She tweeted back at me to say she learned from the best. FEMINIST FEELS.
I au paired for a French family in New York and then in Toronto for about ten months in 2011-2012. I became very close to the oldest, who turned 13 during my time with that family.
She just tweeted a rant about the way a particular school (maybe hers?) enforces dress codes, that is, making girls cover up specifically so they don't distract boys. She properly used the phrase "rape culture."
I'm not arrogant enough to think I'm the sole person who turned her into a little feminist, but we had a lot of intense conversations inspired by watching Glee together every week. Also we're facebook friends, and she "likes" most of the feminist stuff that I post to facebook. Oh, and as much as I adore her parents, they're pretty Catholic, awkward about discussing sex with their kids, and describe their kids in pretty gendered terms, so I'm pretty sure her parents did not inspire her feminism.
I'm just like bursting with pride because I love her so much and I miss her so much and I was really sad her family couldn't come to our wedding reception, but it was a few days before they left for a vacation in France. She's just matured so much, and I'm so proud of her, and I hope that I'm at least part of the reason that she's already such a kickass feminist as a young teenager.
Also by the end of my year with them, her younger brother stopped making gender generalizations, and prefaced any generalization with disclaimers about his experience and those limitations. He was 10.
And my younger brother tweeted recently that he's started noticing sexism on a subtle level because I've trained him well.
