The Mommy. Once a librarian, always a librarian, even if you don't get paid for it. The one who writes all this stuff.
The Daddy. Engineer. Occasionally reads this blog, but usually just looks at the pictures.
The big brother. Thirteen years old. Has a kind heart, and an easy-going manner. Happy and open and helpful. Loves reading, math and playing trombone.
The little brother. Ten years old. Great sense of humor. Knows things...lots of interesting and unusual things. Quirky and gentle and thoughtful.
