Diesel and Lilly are chasing each other up and down the stairs, over, and over, and over. See, Lilly is quick at 10 months so she races to the other floor, and poor Diesel takes a bit of time to catch up at 17 weeks, so the minute he gets downstairs to be with her she runs up and stares at him, so he starts up, and she jumps over him to get down, this goes on for hours, often with Lilly holding Diesel's favorite toy in her mouth to add a bit of enticement.
