Megosztott hang

When I was around eight, I watched my dad pumping gas and noticed the numbers on the pump — 87, 89, 93. I asked him what they meant. Without missing a beat, he told me those were the years the gas was made… and that newer gas was more expensive. It made perfect sense to me. I accepted it instantly and never questioned it again. Fast forward to when I was about 19. I was in the car with my boyfriend, and we pulled up to a gas station. Trying to be helpful, I offered to pump the gas for him.
