29M and this situation has bothered me for years.

When I was 22, me and my cousins went to an amusement park in the Midwest - the kind that's got roller coasters AND water slides. We got on a ride that was basically a giant swing.

I was seated in one of the middle spots. To my left was a mother (40F) and her daughter (10F). As the swing started to go higher and higher, I screamed bloody murder. I've never been great with heights.

I felt something aggressively bumping my arm and when I looked, it was the mother. She yelled (only because it was loud, not in an angry way), "Can you stop screaming? You're scaring my daughter!" It's hard to be objective about the sound of your own voice, but I don't believe my scream sounds especially bloodcurdling. It is not outrageously high-pitched or anything. After the ride, I told my cousins about it and they were visibly annoyed with the idea that someone is asking people to be quieter at an amusement park.

I've been going with the idea that you can be as loud as you want on an amusement park ride my whole life long. And the way my cousins reacted made me think my assumption was valid. But to this day, I can't help but get conscientious when I scream on a ride and I do try to be a little bit quieter. It just seems like if they design a ride with the express purpose of eliciting terror, it would be unfair to dictate what is or is not an appropriate level of terror to express.

So I guess I'm asking for the internets blessing to be loud and proud at Six Flags. Or maybe I'm totally wrong and I have just this weird little blind spot for a hyperspecific cultural norm. If I'm being (too?) loud at the amusement park, AITAH?
