Most 12-year-olds are all about Whatsapps, Snapchats, emails and what not.
But not little Leanna Williams.
No, what fascinates her are good, old-fashioned handwritten letters.
The young Cornwall girl reckons there's nothing more exciting than getting one of these in the post.
So, having beaten leukaemia twice, Leanna decided to start sending handwritten letters to random sick children around the world, just to cheer them up.
"I've been in hospital myself and I just thought - because I would have liked it - that other cihldren who are in hospital or not having a great time in life could get a handwritten letter as well."
In the notes, Leanne tells the kids to "never give up."
She added: "I tell them to keep going and stay strong. I just want them to feel really happy. If I can just bring a smile to their faces and bring happiness, it's really worth it."
Leanna calls them "daisy letters" as a reminder of her identical twin sister Anastazie, who sadly passed away.
"Daisies are beautiful, simple flowers that bring joy to many people so this is why I have chosen the name Daisy Letters," said Leanna, who has a brother Josh (16) and sister Charlotte (10).
Leanna uses a fountain pen and tries to make each of the letters personal and different.
Her project is backed by her parents David, who runs a charity in Helston, and Aimee, a school counsellor.
She has a brother Josh, 16, and 10-year-old sister, Charlotte.
Mum Aimee said Leanna was grateful for the donations she has received towards stamps and paper and said her daughter doesn't expect a reply.
"We have received a few messages from people," she said. "There is one that stands out, from the mother of a teenage girl who said she carries the letter around wherever she goes, and gets it out to read when things are difficult."
Leanna has also helped to raise hundreds of thousands of pounds for children's cancer charity Clic Sargent when she featured in a number of its promotional films.
