I am responding as a parent as two of my three children live with me. Sometimes they show an interest in a topic, which is new to them, but because I am older, I can see where it is leading. I let them go, because there is no harm done and that is how children learn: through their own experiences. The last thing I want to do is claim seniority and discourage them. I responded to the survey. Maybe he is reinventing the wheel. But let him find his own guard rails.
