We’ve also been talking a lot about maps and relativity. As the car gets closer the map zooms in, so the line between the car and our house stays the same, but obviously there’s less actual distance to go. The other day K asked how daddy could only be 2 minutes away when he had so far to drive. And so ensued a pretty lengthy discussion about distance and maps. It’s a complicated discussion with a 4 year old so I expect it will be an ongoing discussion over the next few weeks.
