Pippin: Mommy, what is this?
Me: It's your new stroller! See, there are lots of windows, even up at the top, so you can always see me when it's zipped. And I put in your favorite blankie.
Pippin: It's very comfortable, but... I don't anticipate doing too much strolling in here. Maybe you should get your money back?
Me: No, sweetie, it's called a 'stroller' because I can stroll while I wheel you at places that don't appreciate doggies walking around.
Pippin: Those types of places are just plain silly.
Me: True, but it'll be fun to be able to take you to...
Pippin: The grocery store where my snacks come from! What are we waiting for? Let's get strolling!
