It isn't about teaching, actually. Maybe that seems strange. But some abilities literally cannot be controlled. They take on a life of their own, in a manner of speaking. Depending on the ability, there may be something specific that triggers it and sets it off, and then it will continue on and on until something can stop it. Sometimes it's environmental, others need another person to step in in some way.

It can be such a pain.
