When Lizzie Met Shelly...

Lizzie: Salut, Shelly! Out for your evening stroll again?
Shelly: Yeah, Lizzie. The pavement feels so smooth after the rain. Say, what're doing up on that twig?
Lizzie: Just hanging out and enjoying some fresh air. I love to blend in, you know?
Shelly: Oh. I thought you were taking a dump. Sorry, what does a garden slug know?
Lizzie: Dots.
