I doubt that Sorrow ever actually had a name, other than the one lent to him by his sorrowful state. He might have had a home once upon a time, I mean a real home, and when he was young, healthy and fun someone might have loved him, just a little. Sorrow’s present home is anywhere on the outside of society, probably quite close to the house he was born in, but a million miles from home.
Sorrow is just another soi dog, on another soi in any village, town or city in Thailand
