Not with another human being because they have their own views, opinions, feelings etc, and you are bound occasionally to rub each other up the wrong way. In saying that you wouldn't be without your friends would you? The world would be a sad place.
My relationship with my dog is pure pleasure, I tell him all my problems, he nods and looks wise, wags his tail, chases his ball and I instantly feel better. I think the best part is he never gives me his opinion, just pure love and devotion.
