Studying?

A lot of the stuff Jeff is learning in school is hands on. Which means he needs to practice on someone. That someone is sometimes me. He made me do it the other day when I was looking at the pictures on the camera. Normally he does all this without his book. But this time he was looking something up, and I got bored. This is what he looks like when he is studying. You can see that he needs a haircut. But he is studying too much to get it done. (If you look closely you can also see that he has a bit of grey hair. The grey hair doesn't show as much when he has shorter hair.)
