Personally, I would never ask even a close friend those questions. I'd just how it all went, how are they feeling and leave it up to them to tell me as much or as little as they want to. So as the others have said, just tell people what you're comfortable with and if they push for info just brush them off casually but firmly with a "oh, I don't think you need to know all the gory details." They should get the message.
