Petting Pets

Of course from icanhascheezburger.com.

Once my dad decided to see how long it would take our dog to get tired of having his head pet--his most favorite thing in the world. All it took was 8 minutes. I wonder how much of my attention each of my students would need to feel fulfilled, happy, and like I can stop petting their heads.

I'm pretty sure whatever it is, it wouldn't be enough for me.
