I believe I was on the right track with the information I gave, although it took some time for me to come up with the names of the two reporters from the Washington Post who broke the story (initially I could only remember that Robert Redford and Dustin Hoffman played them in the movie).
I wondered, how could Tricia not remember events that were so prominent at the time? And then I realized that while I was a young adult in the 70’s, Tricia was in elementary school. She was probably no more concerned about Nixon in the 70’s than I was about Khrushchev or McCarthy in the 50’s – we heard about the events surrounding these names, but we weren’t quite at the age to fully understand. Yet these were people and events that shaped the country.
Conclusion: It’s all about perspective.
