When it came to her finances, Tegan Langley admits she had been pretty down on her luck recently until a stranger turned her world upside down one afternoon in a McDonald's parking lot. Frank Somerville of KTVU shared Tegan's experience in a Facebook post [1] on Feb. 24, and the random act of kindness [2] has gone totally viral.

Tegan explained that she was just killing some time before an upcoming appointment when a stranger named Tony approached her car window with a burning question. "He asked if I knew about the state of my tires. I explained that I knew I needed new ones but at the moment simply couldn't afford them. He asked me if I would follow him to Bridgestone Pimpama across the road to see what they could do for me."

Apparently Tony, arguably the most generous man ever, wouldn't take no for an answer. "This complete stranger, Tony explained he couldn't live with himself if he walked away from the situation knowing they were about to blow at any time," she said. "Tony didn't expect anything in return, just asking that one day when I'm in the position where I'm able to help someone that I pay it forward [3]."

And for the record, buying new tires for someone isn't exactly a small favor. Tony also chipped in for some other work Tegan needed on her car without leaving so much as his digits behind. "535 dollars, a lot of tears on my behalf, a few hugs, three brand-new tires, a wheel alignment and the offer to fuel up my car. Then he left. No last name, no contact number. Just Tony the gentle giant with his two beautiful sons teaching them a life lesson."

Now, Tegan is hoping the Facebook post makes its way back to Tony so he knows just how grateful she is: "Tony if this ever reaches you, thank you! Thank you for your utterly selfless act, your kind words, for restoring my faith in humanity. From the bottom of my heart thank you!"
