We homeschool now and it has made our lives far easier, aside from the snotty side comments. I generally decide whether or not I care what this person thinks of me. If I care, I try to bring them along with good stories and invite them to spend the day with us or see my DS's work. If I don't care, I have a stockpile of equally snotty comments back :-)

"When are you going to send your child to real school?"
answered "When are you going to stop pretending yours is "real?"
and nicer "We do a lot of what you might consider real school, we just do it at our own pace. Come hang out with us one day and try it!"

"How can he possibly socialize if he's at home?"
answered "I don't know, I never thought about it since he's always locked in the basement."
and nicer "We have tons of activities that keep us out of the house most of the day- with a wide age range of people. I think he gets more social time now than he ever did in a classroom!"

There are lots of DYS moms and very, very gifted mom bloggers if you look for gifted homeschooling or academic homeschooling you'll find several. Just know you're not alone :-)
