About 20 years ago, I lent $1000 to a friend who was down on his luck (and perhaps a little mentally unstable). I believed he would repay me someday, but he gradually drifted away and left town. I have no clue how to get in touch with him now.
Is there any chance I can take this as a non-business bad debt ? Any effort to collect the debt would begin with tracking him down, which I doubt I can do; his first and last names are VERY common ones, I don't even know what state he is in, and I have no clue as to his date-of-birth or Social Security number. Similarly, it's a stretch to say that 2020 is the year in which the debt became worthless; if anything, that would be the year I became unable to contact him.
Am I out of luck here ?
