person A: I received a call a few months back that my dad had been taken to the ER.
person B: Oh that's terrible. Is he okay?
person A: Well_comma_ it turned out that he'd had a stroke.  Fortunately they gave him the clot busting medicine really fast and he's recovered completely and is back at work.
person B: That's bad_comma_ but really good that he is fine! I am very glad for both you and him.
