Why Do We Homeschool?

So, here's a different question. Well, the question isn't that different, just the asker (askee?). I've read many different answers that people give to strangers and family to the question of why they homeschool. What I want to know is, what did you tell your children when you first got started? My girls love being home with mom, but sometimes want to know why they don't go to school like the other kids. I usually give them a pretty vague answer that Mom and Dad have decided that's what's best for our family, but I don't go into philosophical detail. What have you told your kids?
