I agree with you whole-heartedly going to something like this drunk is an invitation to say the wrong thing to somebody. And I am shocked at their lack of manners, to bring up such an unpleasant and outdated topic. Personally, I would have been tempted to answer their question with a question, such as, "Why are you talking about this to me now, but didn't say a word when it was going on?" Chris might not have liked that any better. Or, "well, do you know who your husband is sleeping with?" For them to bring this topic up with you is beyond rude it is cruel.
