Riley has learned to play "Possum."</a> When he's had enough of you and doesn't want to talk to or look at you, he will pretend he's asleep! He'll close his eyes but keep one or both of them slightly open on the bottom, so he can look out at you to see if you've gone away. If you're looking at him, he will continue to play Possum until you avert your gaze! He's smarter than we all think!
