SINGAPORE - Kindness begets kindness - sometimes it's true.
This week, a British student raised £21,000 (S$43,000) for a homeless man in Preston, England, who offered her his last few pounds to a taxi home.
The homeless man, known as Robbie, offered £3 to Ms Dominique Harrison-Bentzen when she lost her bank card after a night out. She later found that others had similar stories to tell about Robbie - how he returned wallets to pedestrians and offered others his scarf to keep warm, the Guardian reported.
She asked people to donate 3 pounds each to Robbie, and as part of the fund-raiser, she and some supporters spent a night out on the streets.
Robbie has since found a home, and has insisted that some of the money be used to help other homeless people, according to the "Help Robbie, Preston's Homeless Hero" Facebook page.
Stories like these go viral because they warm our hearts and remind us that there is still plenty of good in this world.
Here are some heartwarming stories from Singapore and around the world to brighten up your day:
A video posted on Facebook by user "Yvonne Hairstyles" earlier this month shows a group of foreign workers scooping a bedraggled cat from a drain gushing with water.
In the video, one of the men carries the cat out of the water, while another man provides a traffic cone which they place the cat into.
Ms Noriza A. Mansor did not move away from a stench at the FairPrice supermarket at Toa Payoh HDB Hub, where she works. Instead, the bedsheet promoter got as near as she could.
The smell was coming from Mr Tan Soy Yong, who had soiled himself while grocery-shopping with his wife, who moves around in a wheelchair, in October. He had faeces on his shorts and shins. There was also a small lump of faeces on his sandals.
Armed with a pail of water and tissue, she cleaned him up, and even sent the couple all the way to their home in Potong Pasir.
When a shoe rack appeared outside the new home of Mr Priveen Raj and his wife in November, they were mystified.
It turned out to be a gift from Mr Raj Kumar, a contractor with Straits Construction Singapore. He wanted to thank the couple who often gave food and drinks to him and other workers who worked on their building project.
Four people rushed to help a man who was having difficulty crossing the road in front of City Plaza in this incident that happened in October.
The disabled man was using his hands to drag himself across the road, and two shop assistants came to help him. Two pedestrians then ran over to help as well.
A motorist filmed the kind deed and submitted the video to citizen journalism website Stomp.
Motorists waited patiently for the man to cross the road, even though the traffic lights had turned green.
Seven people stopped to help a man in his 60s who had been knocked down by a lorry in Joo Chiat in April.
One staunched the flow of blood from his mouth and nose, another tried to reassure him, others directed traffic away, and called the ambulance.
"The lorry driver immediately went over to check on the man, and a number of passers-by stopped to help," said an eyewitness, Mr Goh.
In a video that went viral in November, dozens of strangers came to the rescue of a woman pinned under a car.
The CCTV footage of the accident in Zhejiang province showed a car mowing down a motorcycle. It ran over a woman who was riding pillion on the vehicle.
Dozens of people rushed over to lift the car, and get her out. She survived, Chinese reports said.
During a massive snow storm in New York in November, Bethany Hojnacki and her husband stopped to help another trapped driver.
The heavily pregnant Bethany went into labour early, and luckily for them, the driver they had helped turned out to be a paediatric nurse, according to media reports.
Baby Grace was delivered at a firehouse - with the help of a maternity nurse who also happened to be stranded there due to the snowstorm.
An Alabama woman stole five eggs to feed her starving family two weeks ago, but was caught when they broke in her pocket.

American Raleigh Callaway had kidney failure and was in need of a transplant, according to USA Today. The police officer posed for a photo with his wife and their daughters holding a sign that read, "Our daddy needs a kidney!". It went viral.
Chris Carroll, a health care consultant from Texas, ended up being a match, US media reports said. The transplant operation in February was successful.
Luke Cameron started his daily good deed challenge last January in memory of a close friend who died from cancer in 2013.
Deeds include buying meals for strangers, making lemon drizzle cakes for friends and family, and doing chores for the elderly.

The consultancy for not-for-profit organisations engaged Cameron as their National Philanthropy Manager, and he gets to travel around Britain helping a different charity each week.
Unable to pay for the operation their dog desperately needed, a Florida couple was forced to give Lola up to an animal rescue group.
Sumey and David Hageman, however, received the best Christmas gift possible when vet Michael Wong performed the US$6,000 (S$7,933) surgery for free. Wong decided to surprise the couple after seeing how heartbroken they were at having to give the dachshund up.
Despite having stitches, Lola was elated to be reunited with its owners.
An 87-year-old woman in the United States, rushing to the side of her seriously ill son, was pulled over by the police and accidentally dented a patrol car after being given a warning.
After being told that Ms Helen Smith was making a 563km trip north, the policemen brought her the rest of the way to the hospital in which her son was warded. "Four good-lookin' patrol boys brought me," she said.
Ms Smith's son died on Dec 14, but thanks to some kind-hearted policemen, she was able to be by his side.
