(racetrack event / waiting for pickup / suspension explanation)
I’m at the My Company racetrack in Hometown, near the library parking lot, for an event. Sister and Sister’s Husband go home, and I stay for a while before calling to get picked up.
As I leave, HS Chinese Teacher’s son from my school trip to China comes to pick me up. We cross the street toward the Belfry, and he runs down toward the park to get his car. I move closer to the racetrack parking lot so he doesn’t have to come as far.
He gets stuck in a line trying to get his car out. I end up waiting in a different line where people are getting rental cars. Near the back of a large group, people are dressed vaguely as Mario and Luigi. I pass by a pair talking about using a AAA card to rent. Apparently the card will be wrapped by the service. The rentals are only for use around the racetrack and have to be returned if you go farther. This is meant to prevent pollution by keeping the cars within the same climate area.
I’m near a group with a dad and a girl dressed as Mario, a man dressed loosely as Luigi, and another man in a black hoodie. The man in the hoodie is confused about the racetrack and keeps talking about suspension. He jokes that they must be proud of creating a little ball, clearly not understanding what suspension is.
I interrupt and try to explain. I say that suspension involves the front forks and rear cushions, using springs and oil. The man tries to cut in, but I keep going. I explain that the oil has a property where its mass doesn’t change when compressed, and when it’s forced through a small hole, it resists compression and maintains its volume, which reduces how much you feel bumps.
