Shaunnah Hickinbottom must have kicked herself when she realized that she left her phone on the train. But she likely didn't anticipate that the person who would find her iPhone would be so empathetic. Enter 12-year-old Josh Brown of Alvechurch, Worcestershire.

Brown was riding on a train headed to Birmingham when he noticed the unattended iPhone, The Telegraph reports. Eventually, the phone began to ring, so Brown did what was logical and answered the call, hoping to get some information about whose phone he now had possession of. On the other line was Michelle Hickinbottom, mother of 16-year-old Shaunnah.

An agreement was now in place. Brown would drop the phone off at a ticket office and leave a note with his home address listed, as Hickinbottom wanted to send the boy a reward. But when she arrived at said ticket office, she was in for a heartwarming surprise. Instead of his address, Brown left a note: "Don't worry about the money, just do something nice for someone else."

"I was choked when I saw the letter," Hickinbottom told the Daily Mail, "I was really overwhelmed." Hickinbottom explained that the phone meant a lot to her daughter, as it contained a number of personal photos. 

Hickinbottom then took to social media to find Brown. She wanted to reach out to the young boy and tell him how grateful she was. Her Facebook and Twitter posts were shared thousands of times and eventually led Hickinbottom to Brown. "I just wanted to find him as I thought it was a lovely thing to do," she told the Mail.

As for Brown, he was just doing what was right. "My dad always says 'what goes around comes around' and if I lost my phone I would like to think someone would do the same to me," the 12-year-old remarked.
