    Imagine someone who has spent the majority of their life sitting with a sign on the side of the road and that very person giving someone their last 20 dollars. That’s exactly what Marine Corps veteran (退伍军人) Johnny Bobbitt, 34, did in October in Philadelphia.

Bobbitt served in the U.S. Marine Corps and worked as a paramedic (医务辅助人员) in Vance County, N. C. before he became homeless. Nobody knew how he got to where he was because he was discreet about that.

One night in October, Bobbitt was sitting roadside with a sign in Philadelphia as usual, when Kate McClure of Florence Township, N. J. was driving home down Interstate 95 and ran out of gas. Scared and nervous, she got out of the car to head to the nearest gas station. As McClure was heading to the nearest gas station, she ran into  Bobbitt and he told her to get back in the vehicle and lock the door. Minutes later, he appeared with a red gas can. He’d used his last $20 to buy her gas.

After that unexpected meeting, McClure and her boyfriend, Mark D’Amico, who both live in New Jersey, visited Bobbitt several times to deliver gift cards, cash, snacks and toiletries. They then decided to create a fund raising page so he wouldn’t have to spend the holidays sleeping on the street.

McClure started the GoFundMe page on November 10. With the page, the couple hoped to raise $10,000, enough money for his rent, a reliable vehicle and up to six months’ expenses. Bobbitt’s story ran in a local paper. By November 15，more than 10,000 local people had made donations through the GoFundMe page and more than $300,000 had been raised.

On Thanksgiving, Bobbitt was resting in a hotel, his feet up on the bed, drawing up a grand plan for his new life, thanks to several thousand dollars raised to repay him for a good deed.
