While many genuine and satisfactory transactions occur on websites such as eBay or Carousell, it is probably fair to say that such sites are not typically the source of random acts of kindness.
Yet, an act of kindness happened on such a site.
This Seller received a message requesting pictures of three specific pages from a textbook she (or he) had listed. Several messages to and fro later, it transpired that the buyer was a kid who had left his (or her) textbook in school and needed it to complete his homework. He was honest: he didn’t want to buy the book. He just needed those three pages required for his homework.
The kid had not been able to reach his friends (who apparently had long gone to bed) nor could he find the relevant pages anywhere else. In desperation, he searched for the textbook on Carousell, found a copy and put forth his request to the presumably bemused Seller. Where others might have brushed off the kid’s request, the Seller obliged.

We could, of course, ask why the kid was still up at that hour trying to complete his homework. Or how he ended up on that site. Or wonder if we would have done the same in the Seller’s shoes.
Or we could applaud a kid’s solution to his problem – a study in thinking out of the box. And appreciate a seller’s generosity to a stranger in need.
Thank you, Seller, for your kindness in sending those three pages.
