good question. I can understand being offended if someone said that too...especially in that way. I have all different answers to this question depending on who asks. Sometimes I joke and say it's from him watching baby einstein if it's someone that knows how sarcastic I am. But I actually usually answer that it was a fluke thing, some strange combo of genes...although not quite in those words. I don't put myself down or anything, but our DS is PG and is just so much different than us that it's quite unusual. Dh was in a gifted program and I was never tested but could be MG possibly. Who knows...but what I do know is that we are not PG.
