Home Schooling Pre-Preschool?

That was a weird question asked of me. Why wouldn't I want to teach the kid the alphabet, colors, numbers and how to program in Fortran? I figure I can also give the kid opening introductions to film theory and appreciation of speed metal of the '80s. Would be nice to send her off to kindergarten with the ability to tell the teacher that she really hasn't a clue about the deeper meanings of "Raging Bull."
