Mark Twain said this quote
“ I had to have company -- I was made for it, I think -- so I made friends with the animals. They are just charming, and they have the kindest disposition and the politest ways; they never look sour, they never let you feel that you are intruding, they smile at you and wag their tail, if they've got one, and they are always ready for a romp or an excursion or anything you want to propose. ”
