Bailey is still the one that makes Brandon laugh the hardest. Funny thing is, sometimes all she has to do is turn around in a circle and look at him; that's all it takes for him to crack up. It's the funniest thing to watch/listen to. This video was taken a few days ago and while it's Tom making the noise, Brandon thinks it coming from Boo. As a matter of fact, when Tom came out from hiding (behind Bailey) and Brandon saw it was actually him making the noise, Brandon just stared at him with this look that said, "what are you doing??". Then, Tom hid back behind Bailey and made the sound again...Brandon looked at his sister and (as you'll see below) cracks up. Their relationship is already so sweet. It's almost as if they have a special language and they're laughing at a joke that only the two of them get :)
