The hardest thing by far about my vocation is the travel, and the hardest thing about travel is coming home.
No, it isn't returning to my dear Penelope (nee Karen) that is so hard. It's returning to a world that has kept on moving without me, both at home and at work. And it has been moving without my guidance or oversight or sovereign rule.
Again, don't misunderstand me. I don't even mean the people - I just mean the world. It keeps on changing and adapting to changes around it.
