That is so sad on many levels. It probably is a good thing you didn't reply, that woman sounds like the type to have a fight right in the street. Sometimes it is so hard to ignore ignorance and cruelty, but if there is no way you can help, don't get involved. We can only hope that that child gets good teachers in school, because he is not going to learn much at home. It is really a shame that our poor underpaid teachers are the only defense we have against poor parenting.
