While putting together my syllabus, I went looking for an appropriate quote or two (I usually stick a few in there, if only for my own amusement). I came across a perfect one for the Unknown Daughter. As I've mentioned before, she's extremely bright (I know, I'm biased). But she also hangs out with a great bunch of kids - she and her closest three girlfriends are all smart, creative, and nice. They now can have a group motto.
The quote (attributed to Mark Twain) is:
Knowledge is PowerEven better, you can buy a t-shirt with the motto at Cafe Press.
