But time and time again I’ve been uplifted by the kindness of strangers: the man who lifted my stupidly heavy suitcase up three flights of stairs at Highbury and Islington station; the taxi driver who stopped the meter after a lengthy road diversion, then drove on and made sure I got safely to my front door; the older lady who shared my pain as we waited for an hour at Turnpike Lane for that mystical "replacement bus" one Sunday afternoon.  Don’t get me started on my reacquaintance with cancelled/delayed/disappearing tubes, trains and buses: why can’t engineering works be done overnight when all motion stops anyway?
