Fin gets attached to a song and insists on listening to it over and over. On the drive to the St. Louis Zoo, for example, 'Ain't No Mountain High Enough' was on a loop the entire trip.

But more recently she's been stuck on the Gotye song, 'Somebody That I Used To Know'. On a drive to Carbondale I watched her in the rear view mirror as she grooved to it, nodding her head with her eyes shut.

When the song ended she looked at me with a sorrowful expression on her face.

"Mom, I like that song because it reminds me of my boyfriend at daycare, Nate. But Nate doesn't go there anymore and I'll never see him again and it breaks my heart! He's somebody that I used to know!"

It was a struggle to keep the vehicle on the road.
