"That handful of us who became Mike's water brothers without learning Martian.  The others ordinarily do not share water and grow closer until they pass from the Seventh Circle to the Eighth... and by that time they are beginning to think in Martian.  Heck, some of them know more Martian by that stage than I do now, since I'm a 'First Called' myself and started my studies after I was already in the Nest.  Oh, it's not actually forbidden to share water with someone who isn't ready for Eighth Circle.  Hell, if I wanted to, I could pick up a babe in a bar, share water with her, then take her to bed - and then take her to the Temple and start her on her apprenticeship. But I wouldn't want to.  That's the point; I wouldn't even want to.  At the very most I might decide that it was worth while to bring her around to an outer service and let Mike look her over and find out whether any of it clicked with her.  Ben, I'll make a flat-footed prediction.  You've been around a lot - I'm sure you've been in some fancy beds with some fancy babes."
