How do you act when your parents return home?
Pocket: I am in my crate. I bark, and when I am let out I run around their feet sniffing them.
River Song: I wait by the kitchen window. When I see their car pull into the driveway I put my head back and howl. Then I go to the front door and jump up and down. When they get inside I need to be touched. Then I pant for half an hour because I am so excited.
