I have definitely become less patient with this type of thing. But long before I was actually dx, I didn't feel well and it took energy to just talk and have a normal conversation, much less a stupid one! So I've been known more often than not, to say absolutely nothing and walk off. Or say nothing and just stare at them until they walk off.
This may sound not so nice... and I really am a fairly nice person. But it's just about SURVIVAL!
I just can't take on all the stupid people in the world!
ANYWAY, natalie, it sounds like this person was just being rude and nosy, which is a whole different thing than just stupid!!!!!
