Imagine being a little debugger making your way through a Ruby program. You jump from statement to statement until you finally hit a breakpoint. Now, catch your breath and look around. See the scenery around you? That's your scope.

You can see bindings all over the scope. Look down at your feet, and you see a bunch of local variables.
