question 66

Multiple Choice

When Noah's dad gets home from work, Noah runs to him shouting, "Daddy!" His dad sweeps him up in a bear hug, then gives him a gentle knuckle rub on top of his head, then lowers him to the ground in a pretend choke hold. Noah screams with delight, escapes the hold, and climbs on his dad's back to ride him like a horse. Inadvertently, Noah hurt dad while climbing, and his dad said sternly, "That really hurt. Be nice!" What kind of lesson is Noah's dad teaching him with this rough-and-tumble play bout?
