Osgood goes to the optometrist

My son and I were outside in the garden and he was fascinated by my description of what a mole is..

"A little animal that digs tunnels under the ground and eats bugs and plants.He's got little tiny eyes and cant see very good."
He immediately wanted to go inside and look them up in my National Geographic Encyclopedia of Mammals... he sat on my lap and we read all about them.. cute little devils.
