The story speaks for itself. The “need for details” smacks of voyeurism and an almost deliberate attempt to miss the point of the letter.
The bottom line is. Do you know someone like the person depicted in the letter, male or female? Do you make believe they dont exist or do you try and reach out to them with a smile, a good morning, a hello and if able an invite? Do you treat the “yaffas” of the world, their parents and siblings like lepers to the point that you ask that be sent out of the machne so to speak, like a metzora? Thats the message the letter writer is trying to make. Wake up and smell the coffee. If you did this to Yaffa, ask for mechila and prove you mean it by not kicking the next yaffa to the curb.
