Me too. 5th grade, 1970.
We had a great teacher, And she taught about the constitution. She said everyone thinks that just being born in the states makes one eligible, but, she said, some believe you must be born to US citizens.
I remember it like yesterday. She was hands down prettiest teacher I ever had. I remember every minute in that class, LOL.
I remember the lesson, but I don't remember if it was a trick, extra credit question on the test or if it was in a class discussion on it, but I definitely remember the part about being born overseas being a potential dis-qualifier.
Vietnam was still on and the kids in class who had been born overseas weren't pleased.
Looking back, I didn't think the schools then were all that great, just from what the adults said at the time, but compared to now? Damn...how far have we fallen? What happened to us between then and now?
