The nicest things that have happened in 2015 - so far

'Dancing Man' told to keep on dancing
It all started when two pictures of a man dancing were posted online with the caption: "Spotted this specimen trying to dance the other week. He stopped when he saw us laughing." The cruel comment prompted a global online search to track him down and put a smile back on his face. Dancing Man was revealed to be a Londoner called Sean, who has since been invited to a private dance party in LA in his honour. And just to keep the good vibes going, Moby says he will DJ.

A stranger brought joy to a mugged pensioner's life
When 21-year-old Katie Cutler heard how a mugger viciously attacked disabled pensioner Alan Barnes on his doorstep she wanted to find a way to help. She set up an online donation page to raise £500, but a week later she was handing over a cheque for £330,000. The money allows him to move away from the house that holds such bad memories - and closer to his new friend Katie.

A model with Down's syndrome made fashion history
Jamie Brewer is best known for her acting work - but in February she became the first person with Down's syndrome to walk the runway at New York Fashion Week. Designer Carrie Hammer asked Jamie to wear a black belted A-line dress on the catwalk as part of the “Role Models Not Runway Models” campaign - and she absolutely stole the show:

Devoted owner made her dying dog's last days extra special
When Lauren Fern Watt discovered her best friend Gizelle had terminal bone cancer she decided to concoct a bucket list of adventures to make the most of their last days together. The 160-pound English Mastiff visited Times Square, spent a day at Washington Square Park, went to a party to "meet a cute boy dog", found the best doughnut in the world and even met Santa.

Little boy posted a letter - for the postman
A little boy who thought "the mailman should get post too” penned this adorable postcard: “To Mailman. Don't send this to anybody. This is yours. Sincirilly, [sic] Olivier." The youngster clearly realised it must be tough for postmen who spend hours delivering thousands of letters every day without ever seeing one addressed to them. His mother said the postie shook his head in disbelief when he received it, but was clearly delighted and walked away chuckling.

Uber driver delivered a small act of kindness
Hairdresser Josie Chan was left speechless when her lost wallet - complete with bank cards, driving licence and cash - were returned in the post by the Uber driver whose car they were left in. She was even more touched when she realised he spent £6.40 sending it back - more than he earned from £5 taxi journey. She thanked Jamshid with a box of chocolates and a £10 note to cover the postage.
