I’ll tell you a little story that’s not about apes but about my dog. I have a back yard that is fenced and accessed by Bootsy(the dog) by a pet door in the back door. The front yard is a common area so to speak as it has no fence and is only accessed by my letting him out of the front door. The other day as I am sitting at my puter looking out my window into the back yard I see Bootsy talking to his friend Jake( neighbors dog) through the back fence. Suddenly he runs back to the house and runs into puter room and “tells” me he needs out into the front yard. I get up and let him out and his friend Jake(neighbors dog) is waiting for him and they both run and play. Now that sounds simple enough but think about it. Bootsy had the thought process to understand and figure out to come ask to be let out the front to go play with his friend.Say what you will but that is a very complicated thought process for an animal. There is no such thing as a dumb animal, just ignorant humans who are too blind to see.
I agree, although I've known some retarded pets.
