So Z, the now married Z, has just popped in. How startling, and how curious. One immediately feels the need to check on the significant other - "So, how's Ruth?" - and what one really means is, "How's Ruth and how the hell is married life anyway, are you regretting it, do you feel chained up, is it stifling or are you both blooming?" Z has not changed. Did I think he would change? I honestly don't know. He has changed, deeply but not superficially, since I first met him. You have to know Z to understand how that is possible. But it is.
