I know the feeling... Both feelings. My wife always giving me greif about carrying everywhere we go. And constantly worrying about it peeking out. I'm always in HW stores reaching, bending, loading lumber... And I'll admit many times in only in a t shirt.
We were taught in ccw class here in IL, that the gun must be concealed, or mostly concealed. He explained that it ment if you reach for that high shelf and some one sees it, its not a crime. Not a good idea, of course, but not a crime. Other states (fla perhaps?) Consider it brandishing even if the gun prints slightly. That's outrageous. I feel like it could lead to some problems.... Your ex-GF knows you carry. Sees you out and about, calls the cops saying she saw a gun, meaning (in the eyes of the law) that you threatened her with a gun. Something like that.
