History Lesson

I was playing TaxiMom for WiseKid this afternoon and drove out to pick up his girlfriend, also 16. We got into a discussion of her schoolwork (groans from the back seat) and I asked here what she was doing in History right now.

"The Vietnam War," she said.

The Vietnam War???? How can that be history already? I mean, I did a big, long term paper on the Vietnam War in high school and it was for Current Events in Social Studies, how can that be considered history already?
