Ever since reading the book, Flotsam, my son has had an interest in magnifying glasses. (In the story, a little boy carefully scrutinizes a hermit crab and photos using a magnifying glass.)
Today the little guy got his very own magnifying glass. He had to examine everything. When he got into my car, he examined my seats.
"Mom, I see a germ here. And here's another one. And another!"
(Gosh. Is my car really that dirty?)
