Jerry Kelly - definitely out of the circle.
FWIW, unless my fellow players are incredibly large, or the greens are unusually soft, I don't care if they walk in my line briefly. The old ritual of having to walk around behind everybody is getting old in the day of spikeless shoes.
I don't understand what you mean, "out of the circle".
My wife routinely stands on my line. Married 27 years, I let it go.
