This work is part of a bigger goal that is , How can we prove that animals can be selfaware ? Episodic memory is linked to selfawareness , so being able to prove without a doubt that this is the case is great . Also note that researching with dogs ' behavior is quite difficult because of the fact that they are able to read our reactions very accurately , even our tiniest microexpressions . This might interfere in any experiment which requires that the dog acts by its own will . <| sep |> First it was because his job was keeping him until 4 AM instead of 2 like he was scheduled . It was his last night at this location anyways . Then it was because he only got four hours of sleep and he didn ' t feel like going to dinner with his family , but for some Godforsaken reason he agreed to be chauffeur for his mother and sister , ensuring that he is unable to escape uncomfortable family situation at all . I invited him to spend it with us , but he ' s going to his other friend ' s before his family for a few hours . So apparently I ' m good enough to vent and whine to , but not actually spend time with . Nice .
