@bhawthorne it's not a trick question but it might feel that way. "Would you want X for your child?" is another way of asking, "Do you think X is good for someone? Or is minimally harmful?"
Because for many of us, we want what's best for our kids more than almost anything, so it's a way to think about an option with the utmost care for the participant.
It may be specific to your family; if your child is passionate about lacrosse, sports might be the best option for them, if not for everyone.
