It is not scientific to say that they are hungry when they're hunting and they're tired when their tongues are hanging out, and then say when they're playing with their children and acting joyful and happy, we have no idea if they can possibly be experiencing anything.
Tidak ilmiah untuk mengatakan bahwa mereka lapar ketika mereka berburu dan lelah ketika lidah mereka terjulur, lalu berkata ketika mereka bermain dengan anak-anak dan bertingkah riang dan gembira, kita tak tahu apakah mereka bisa saja merasakan sesuatu.
