I think in this case it was likely "a professor thing" just as LNEsMom pointed out upthread. My DH is an art professor and I am a SAHM. Many of his colleagues from other fields don't know quite what to make of me and I have had several be rather dismissive and rude at university events. Many more though seem to have a level of envy that I am able to be home with DD (more men than women I might add). In my experience a lot of professors can lack social skills and look for "evidence" to prove a theory in what the average person would view as a normal, everyday conversation. I probably would have answered with my actual opinion of where it came from. If he is interested in your son and you were labled gifted as a child that would fit his theory. Why a gifted parent chooses to be a SAHM would probably have led to more in-depth and perhaps meaningful discussion. It would have been great fun to enlighten him:)
