I’ve seen this often. My son is 3 and often tells us his reasoning: “we need to run for the bus because it doesn’t wait for us!” He always says it like he isn't sure we know about buses yet making me think it’s hard to model others as separate minds with differing information until much older. But his modeling of the world logic is very solid. He can easily use multiple tools to reach high up snacks, or build complex block forts, or reason about what will happen “we will grow up and then go to kindergarten!”
