Young chimpanzees will groom each other in much the same way an adult would.
They are sometimes resistant to letting their mothers groom them as they would rather
be playing. After playing you move over to sit with your mother and other chimpanzees.
One of the chimpanzees starts grooming you by picking at the leaves and dirt stuck in your
hair.
Several chimpanzees are moving out to find food. You are getting hungry but also see
an opportunity to taunt another chimp into a game of chase. Would you like to feed or play?
