When you’re a kid you wake up in a different place than where you went to sleep all the time. That almost never happens as an adult and if it does it’s not a good thing. If you wake up in a different place than you were when you went to sleep it probably means you’re in the hospital, jail, or you were so out of if they you have memory loss. Think how disorienting that would be.
I don’t know a thing about cognitive development in children but I’m guessing they haven’t made the connection of traveling in a car with arriving at a new location, they can’t make that leap yet, so it must seem like magic to them. They were at home and now they are at the store, whoa.
Just saying.
