Context: While I was in college my dog ran away back home and was never found.  My mother had been taking her on a walk in a park and my dog fell down a cliff.  I dreamed about her every night for a month at school, and hoped I'd get a call saying she was found, but she never was.
Speaker 1: My dog disappeared while I was away at college.
Speaker 2: That's so sad, I'm so sorry you had to go through that. How did it happen?
Speaker 1: My mother was walking her in a park and the dog fell down a cliff.  She was never found or recovered.
Speaker 2: My goodness, that sounds like a tragedy. I'm sure she was a great dog friend of yours.
Speaker 1: Yes, I loved her a lot.  It took a long time to get over but it was quite a long time ago at this point.
