Well, how rude. This video doesn't play the sound. So, I'll have to explainn so you aren't completely confused.
Max has figured out how to go upstairs. But -- he has not figured out how to go back down.
This is him, sitting at the top of the steps, whining as loudly as possible at me. He's obviously annoyed that I'm sitting at the bottom of the stairs video taping him instead of coming to his rescue at the top.
