OK, allow me to try yet again to clarify.
the bochur, by picking up the papers, no matter what kind, did indeed do a real Kiddush HaShem, AGREED, and a sincere yasher koach.
My question, and really only a question was, would the author of the original letter shep nachas and acknowledge this Kiddush HaShem if the paper was anything other than “heimeshe”. I ask this because he, the author specifically said that he could not get why a bochur would clean up a city bus, until he, the author, realized that the papers were “heimeshe” –so I hope that clears things up, but just to reiterate, the bochur did a beautiful thing, yes; why is it that the author couldn’t chup picking up papers until he, the author, realized they were “heimeshe”
