Giftedness, issues, whatever aside, kids are often better at home than around the general public. They know it's safe to decompensate with Mom. It's safe to act up when they're tired, out of sorts, or just feeling ornery. Mom, unlike that weird lady at the grocery store, is not likely to kill and eat them if they misbehave. Whereas Weird Lady...we're not so sure about.
