person A: My dog pooped on the rug today. I was so mad!
person B: Oh no! Did your dog have to go really bad or what happened?
person A: She's a mere puppy_comma_ so she is learning. But she was doing such a good job going outside then all of a sudden she goes inside! I was not happy.
person B: Hopefully with enough training your puppy will let you know when she has to go. It takes time.
