Come back, come back, dear friend, only friend, come back. I promise to be good. If I was short with you, I was either kidding or just being stubborn. I regret all this more than I can express. Come back and all is forgotten. It is unbearable to think you took my joke seriously. I have been crying for two days straight. Come back. Be brave, dear friend. All is not lost. You only need to come back. We will live here once again, bravely, patiently. I’m begging you. You know it is for your own good. Come back, all of your things are here. I hope you now know that our last conversation wasn’t real. That awful moment. But you, when I waved to you to get off the boat, why didn’t you come? To have lived together for two years and to have come to that! What will you do? If you don’t want to come back, would you want me to come to you?
