Mike did not get up to fetch water.  He sent a glass from the tray of drinks into the bathroom, had the tap fill it, returned it to Jill's hands.  Mrs. Paiwonski watched this with almost absent-minded interest; she was beyond being astonished.  Jill held the glass, said to her, "Aunt Patty, this is like being baptized ... and like getting married.  It's... a Martian thing.  It means that you trust us and we trust you... and we can tell you anything and you can tell us anything... and that we are always partners, now and forever.  It's very serious... and once done it can never be broken.  If you broke it, we would have to die - at once.  Saved or not.  If we broke it - but we won't.  But you don't have to share water with us if you don't want to - we'll still be friends.  Now - if this in any way interferes with your faith, don't do it.  We don't belong to your church even though you guessed that we did.  We don't.  We may never belong. 'Seekers' is the most you can call us now.  Mike?"
