The other thing I'd keep in mind in these conversations is that your first responsibility is to your child and that really random strangers (or even friends) and what they think matters a lot less. So, whatever you say, think about if you want your kid to hear it over and over again. I would prefer my child not hear public school is the problem or that there is something wrong/different/weird about him that makes it so it won't work. I'd rather just focus on how we are so happy with what we've got.
