Thanks for that link, Kris777.
ficbot - I know what you mean about the screen getting smudged. There's always fingerprints all over it (and usually some undefined kid ooze - lol). My nephew, of course, tried to taste it once.
You're right about the monkey-see-monkey-do, at least in my own case. We had bookcases of books in our living room when I was growing up, so of course I had to explore them. And my parents got those Time-Life science and nature series books that had lots and lots of pictures in them, so they were well-worn by the time the last sibling came along. One of the greatest days in my life was when I got my first library card. My niece now takes out one library book a week and she's in seventh heaven about it.
