True story
About 18 mos ago I stopped in fast food joint to grab a quick sandwich. As I sit in the booth I felt something at my feet which turns out to be some guys wallet. I open it up and there's' some cash (maybe a couple hundred $...I didn't count it) and his student ID. Turns out he lives about a half mile away, so I shove the wallet in large envelope from the trunk of my car, drive over there, and put it in his mail box with his name on it,...anonymously.
Two / 3 weeks ago I go for a long bike ride with a buddy on a Sunday morning. It was a freakishly hot day (like a 103 deg F) for coastal So Cal so after the ride I stopped by the beach a couple blocks from my house for a swim. I shove everything,: keys, ph, sunglasses wallet, in my back pack to leave on the beach. Afterwards I ride home, put the bike away, throw back pack in the closet and dont think about it until later that day. When I go to get my stuff from the backpack my wallet is gone. It must have fallen out on either the walk up from the beach, or the short ride home. Either way it's gone. Some cash but of course the bigger pain in the ass is the CCs and ID's...crap
Long story short, 3 days later and before I'd even made an appt to replace my DL at DMV, mail man delivers a thick envelope with, ...you guessed it,...my wallet, which someone had sent, cash and all...anonymously
I don't necessarily believe in Karma but I definitely believe you generally get what you "filter for" out of life
