I tend to remember stuff the same way (i.e., grade in school or place of residence). Now that I’ve been in the same condo for almost 4 1/2 years, it’s becoming harder to remember exactly when fairly recent events happened.
Slightly off-topic: yesterday I did pub trivia. One question asked the year that McDonald’s introduced Chicken McNuggets, among a couple other events. I somehow remember that I was in first grade when McNuggets were introduced! This narrowed down the possibilities to 1983 or 1984, and we picked the right one (1983).
