Narrator: Around the end of 1969, a funny thing happened: 1970. Not that anyone was paying much attention. Still, with a new decade on the books, maybe it was time to heal old wounds, get over old hurts. It was possible. After all, I'd gotten over Winnie Cooper. Yep, Winnie and I were friends now. That incredible smile, the way she tossed her hair, the heart-stopping lilt of her perfume... I was over that.
