That's my worry ... she likes to debate everything now...why the heck would I want to give her a skill like that?
We have no danger of my daughter not being able to argue a point or questioning us or being shy...not even close. It might be deadly for us as parents if she were to learn debating and excel at it. She already is too good at it for her age.
but a one-off workshop? that seems like a waste of time and energy
If your daughter bests you in an argument, maybe it's because she's right and you're wrong.
