“ Well I can tell you now that married life is not a plateau, not at all. There are ravines and great jagged peaks and hidden crevasses that send the both of you scrabbling into darkness. Then there are dull, parched stretches that you feel will never end, and much of the journey is in fraught silence, and sometimes you can't see the other person at all, sometimes they drift off very far away from you, quite out of sight, and the journey is hard. It is just very, very, very hard. ”
