for some reason, i keep thinking of a Conan the Barbarian comic in which conan is hired to teach three young swordsmen how to fight. at the end of their training, the pupils turn on their master. conan makes short work of them though, leaving his students to die in the snow. "i guess i'm not a good teacher," he philosophizes.
jessica was never my student but she is in college and she shares her work very generously. looking at it reminds me that the next generation is hot on our heels. and they're going to kick our ass.
