I should really just stop going the extra mile for people. Sold my old phone on fleabay. Notified the buyer that I upgraded him to UPS for free and I’ve sent his tracking number. I’ll drop it off on my lunch break tomorrow and he’ll get it by Wednesday as opposed to Friday with USPS.  It cost $10 more but it’s also a bit more dependable than  USPS here. 

Response?  “ok”

I really should just not. 

 @ccf56f0a I usually call this "The evolution of Trust" -  https://ncase.me/trust/

I guess doing it with strangers on the internet does not really give you much, but I find important showing friends random acts of kindness from time to time, and accept people make mistakes.
