Exactly, hes going to bed and needs to turn off all the lights downstairs

that means the game has already been won

But both switches are up, and i doubt the picture was taken with the garbage disposal on.
Where come light?

Natural light

in New Zealand, we call that down.

There's usually a switch for most of the kitchen light(s) and then a switch next to the garbage disposal that turns on a light above the sink. On the house's I work on that's usually how it is at least.
