A childhood belief about physics

When I was about 8, I came up with the idea that no two events could happen simultaneously. I saw time broken up into incredibly short snippets, so that what appeared to be events happening at the same time were actually just one after another, like frames in a film. I would sit watching my family watch TV for a half hour at a time, trying to prove my theory was true. (Misleading choice, because people sitting in front of the TV often look like they aren't doing anything at all). Then it occurred to me that people all around the world were doing things, too, and I'd never be able to watch them all at once.
