[sbaglio]

It's situations like these that make me favor heading such conversations off at the beginning (though I always have some zinger that I could have said, after the incident has happened). When he asked "Is that Japanese baby yours?", that was probably your cue to cut him off because nothing good could come out of his mouth after that comment. But then again, in the heat of the moment, who can say what anyone will answer? Still, you held your own.
