Just wish that her ukemi was good enough so I could show a full speed sankyo, then ask her to pick out weak spots.
Sometimes you just have to show them. I usually try and bring them just to the point where they are about to become a puddle of protoplasm on the mat...and then stop and hold them up before they actually hit the mat (or the wall...or whatever)
Doesn't always work though...not always good enough to stop them from splatting. Maybe in a few years <sigh>
