Kalev blinked and chuckled as she aimed at the 10 ball, "No, vixen, not that one." He shook his head, pointing to the correct ball, "You only hit the white one. The cue ball. It hits the others."
"Here, come over here," he motioned to where he stood. "You have to line up the best shot to get it in the pockets. If you hit it here you can get the one you were aiming at into the corner pocket." With his own large wand he drew a line from one ball to the other and from that ball to the pocket. "Understand?" He almost didn't expect her to, he never claimed to be good at teaching, but at least if she said something he could try to explain it better.
