      I was told that gorillas smile when they are sad and frown when they are happy, but I’m not sure if that was a zookeeper just trying to convince us that a gorilla was happy.

      We do lots of communication through facial expression, it is interesting why this is the same for all humans.

      I wonder if they learn it from their parents? What do you think?
