" his dad sweeps him up in a bear hug, gives him a gentle knuckle rub on top of his head, then lowers him to the ground in a pretend choke hold. nate screams with delight, escapes the hold, and climbs on his dad’s back to ride him like a horse. inadvertently, nate hurt his dad while climbing, and his dad said sternly, "that really hurt. be nice! " what kind of lesson is nate’s dad teaching him with this bout of rough-and-tumble play?
