One theory on parenting that I hear over and over is that one shouldn’t try to be a friend to our kids, because, for instance, if your kids are doing something really annoying or repugnant, they need to be told firmly and directly that it is unacceptable behavior.
Actually, my preference would be that I could talk to my friends the way I talk to my kids:
“Yo, don’t chew with your mouth open!”
“Dude – Don’t be so rude! Can you say that again nicely?”
“Can I have a hug?”
