Yes , I think a quiet word in his ear would be better all round to save red faces if there are stories you do not wish everyone to hear. At my husband's brother's wedding , his best man told the whole wedding party in his speech that he'd 'had' the bride and "Let's face it , who hadn't " because she was a party girl and when they all got to a certain location , "it was a case of , hey hey , it's party time with Miss x" There was a lot of awkward shuffling and coughing going on. The worst of it was though , he continued , becoming worse with even hairier stories , in the belief that it was a cracking speech. Well it certainly was memorable ........ for all the wrong reasons ! Serves my brother-in-law right for not picking my hubby as best man.
