I finally got around to making a short video clip of Isaac turning the lights on for me. For some reason, though, I can't get it to upload onto my blog. But I was able to upload it on Youtube.
So you can watch it here.
It's really cute because when I watch it, Isaac hears me telling him to do the lights. He knows the command isn't exactly coming from me, though. But it's still my voice. So he looked confused at first but then decided he should still turn on the lights. And now when he hears it, he jumps right up.
