In fact, it comes to this: nobody is capable of really thinking about anyone, even in the worst calamity. For really to think about someone means thinking about that person every minute of the day, without letting one's thoughts be diverted by anything- by meals, by a fly that settles on one's cheek, by household duties, or by a sudden itch somewhere. But there are always flies and itches. That's why life is difficult to live.
