I’m not sure when I stopped caring about Giants vs. A’s games.
I come from a three-way split family of baseball fans. It was always about 50% Giants, 40% Dodgers and 10% A’s, and we would go to the Giants vs. A’s games fairly frequently. The Dodger fan portion of the family would either switch to A’s loyalty or just wear their irrelevant Dodger gear.
We stopped getting to games a couple of years later. Partially because that’s just how life goes; everyone grows up and gets busy.
