Now I'm nervous! 6-30-11

I just handed in the kids withdrawal letter to the school administrators and we are now officially homeschooling. Everyone at the office was very nice and relaxed about the whole thing, so that's not why I'm nervous. Also, I seem to be unusual among homeschooling moms in that I have no doubt of my ability to teach my children, so that's not the cause of the nerves either. I do know that I have a lot to learn as I teach them, but am looking forward to the opportunity of understanding as an adult concepts that eluded me as a child. Honestly? I'm at a loss as to the cause of the butterflies. Even so, they're quite emphatically making their presence known.
