I'm kind of old, and so the Rolling Stones speak for me when I'm tired.

Me to the post-op kid: I'm sleeping with the phone so you can wake me up if you need something.

The post-op kid: But I don't want to wake you up.

Me: Well... You can't always get what you want, but if you try sometimes, you get what you need.

A sudden understanding took over her face and she laughed. Me and my little retro metal-head totally understand each other.
