Waterfalls

Sebastien (sleepily, as he woke up from his nap): Mommy, let's go see the waterfalls
Me: Where are the waterfalls, sweetie?
Sebastien: In the mountains.
Me: Oh, the mountains are far, far away. We'd have to get on an airplane to fly there.
Sebastien: Let's get on an airplane and fly there. We're going on an airplane. Let's see the waterfalls.

So I took him to the closest thing to waterfalls I could find in the city. He had fun there, too.
