The young take over from the old.
Maybe that's why so many people delay having children these days, a deep-seated fear that it marks the beginning of your obsolesence. Children become your life, they take charge of it, and when they're finished, you're gone, tossed aside like bread gone bad. Your best years are behind you, chewed up by years of slimy nappies and arguments with stroppy teenagers.
No more writing for me, then.
