She shouldnt have used the word “affair”...I care about my animals, but I don’t characterize it as an affair. She may give other indications that she is a bit unhinged. But it would appear to be normal to regard the life of an animal. RinTinTin, Lassie, Mr. Ed, Old Yeller, Black Beauty, Flipper, Willy, Silver and Scout, Arnold, and others would concur.
English is likely not her first language, and the actual quote may have been in some other language that is being translated to "affair" for click value.
