I can't really say from "experience" - since I was late to the news, however, physical signs I was told was the small pupils - problem is my AH has really dark dark brown eyes, so you can't tell, and he's never been one to look me in the eye - for anything anyway!
I think the thing is that our antenna do go up when something's not right. We might not be able to pinpoint what or why, but somewhere something triggers and you "know". I never thought I'd get this point, and I certainly wasn't going to try, but surprisingly, I see it happening the more I understand this whole thing. Go with your gut.

How's it going today?
