When Reilly Flaherty lost his wallet at a concert in Brooklyn a few weeks ago, he assumed the worst: his cash, IDs and credit cards were stolen and forever gone.

So, like anyone who has lost a wallet, he canceled the credit cards and replaced his driver's license. But two weeks later, he was surprised to receive an envelope in the mail containing some of what he lost, along with a hilariously honest note.

The letter read: "I found your wallet, and your drivers license had your address so here's your credit cards and other important stuff. I kept the cash because I needed weed, the MetroCard because, well, the fare's $2.75 now, and the wallet 'cause it's kinda cool. Enjoy the rest of your day. Toodles, Anonymous."

A flabbergasted Flaherty posted the thief's strangely polite letter on his Instagram account and captioned it, "thanks... I think?"

It's uncommon in New York City to ever get lost or stolen items back, after all. And nothing engenders a New Yorker's empathy like the pain of having to pay ever-increasing subway fares.

Flaherty told NBC 4 New York he couldn't believe the "good Samaritan" went to the lengths he did to write out a letter and actually mail back his half-stolen wallet.

And while the person who sent the items back is technically a thief, Flaherty can't help appreciate the humor.

"If nothing else, it's something me and my friends have laughed about quite a bit," he said.

Another payoff: the Kings Theatre, where Flaherty lost his wallet, got wind of what happened Tuesday night and has offered him free tickets to an upcoming show.

The venue told him to leave his wallet at home.
