person B: Thats sad_comma_ hopefully the new cat got to live a long and full life with you
person A: Well_comma_ we had a funny twist. The same day we brought the new kitten home_comma_ or old cat showed up. We kind of thought maybe he was hanging out close to home and was mad that we replaced him.
