Naya, fetch!

This is how games of fetch usually go with Naya:

1. I throw a tennis ball.
2. Naya runs to the tennis ball.
3. Naya flops down.
4. The game of fetch ends.

Maybe Naya's gotten wise to the fact that if she brings the ball back to me, I'm just going to throw it again, and she'll have to go retrieve it, and the whole thing will be pointlessly futile.  Yeah, my dog is a nihilist.
