"It's when most of the guests have gone that the party really gets interesting - peering under the table and into the bath to see who's stayed and what shape they're in. It is then that those who are still conscious divulge things you had not known before: sometimes about themselves, sometimes about other people and sometimes about you. It does not necessarily make pleasant hearing but it is always fascinating. In the relaxed atmosphere, in the wake of the hubbub, they unwind and grow confidential - nay, indiscreet. If they are not already, they end up as your closest friends."
