['I received a call a few months back that my dad had been taken to the ER.', "Oh that's terrible. Is he okay?", "Well, 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."]
That's bad, but really good that he is fine! I am very glad for both you and him.
