Women in general don't appreciate having their physical personal space violated by someone without express permission of one kind or another. Penelope is not an exception to this, and in fact takes quite a lot of offense at being grabbed, even if it is meant just to steady the poor bastard on his feet. So she shoves him backwards and quickly checks which way round her mace actually is pointed.

"Now I know it's pointed at you. I am not kidding. I am not trying to be cute or funny or play hard to get. I hate you, I want you out of my life and away from me, and I am not going to change my mind because you decide stalking me until I get Stockholm is fun. Leave. Me. Alone."
