"Go easy on me, I don't want to break my brittle old man hip." On the streets, Ollie would usually focus on a spot that someone was stupid enough to let him injure. Hit someone with an arrow and then kick the arrow as much as possible. The important thing was that they regret having raised a hand to whatever man, woman, or small child he caught them threatening.
He didn't do that with Kimber, although if he really were teaching a self-defense class, he would tell her to. She was the worst kind of self-defense student anyway; the point in the classes was to disable your opponent long enough to get the fuck away. She was the type liable to kick his ass nine ways from Sunday just to show she could. Which, all in all, Ollie liked in a woman. It made 'em interesting.
He focused his next kick (pulled quite a bit) lower, looking to trip her up more than anything else.
