A statement like that is usually meant to be a compliment, but it just isn't. It's kind of like saying, "You don't stink too bad for being so old."
It's a backhanded way of saying that your kid is a poor soul for being homeschooled but it's good that you've made the best of it. For those of us that homeschool, we do it with purpose, reason, and to create certain experiences or outcomes for our children. I'm not sure what this "normal" is that you speak of, but I'm not convinced that it is something positive. Normal is conformity. Normal lacks individualism. Normal is not creative or opportunistic or a risk-taker. Normal is actually the problem, not homeschooling.
