I was driving Talia somewhere when she asked me, "How come you have BARK in your car?" [insert look of disgust]
"How come you don't?"
That was the only quick thing I could come up with. And, anyway, if I'm not nice to one of the only two teenagers in my life, she'll quit helping me with my iPod.
But anyway, I'm always collecting things like rocks, shells, feathers, and driftwood on my walks.
