[usr] My friend borrowed a book from me, but he went and lost it! It was one of my favorites too [sys] Oh that's terrible.  Did he say how he lost it? [usr] Yea, he accidentally left it out in the rain. So of course it's no good anymore [qst] ask me for further details [bhv] [None]
Do you remember the title?  Maybe you can get another copy.
