A seven-year-old boy who sent a birthday card to his dad "in heaven" received a touching letter from the UK postal service to say it had been delivered safely.
The Royal Mail letter assured Jase Hyndman, of West Lothian, Scotland, that his card had made it through the "difficult" journey.
Posting the letter on Facebook, mother Teri Copland said: "I cannot state how emotional [Jase] is, knowing his dad got his card. Royal Mail, you've restored my faith in humanity."
In response to Jase's request to send the card to "heaven", Royal Mail's Sean Milligan said: "This was a difficult challenge avoiding stars and other galactic objects en route to heaven. I will continue to do all I can to ensure delivery to heaven safely."
The Facebook post with Royal Mail's response to Jase was shared more than 200,000 times.
Every year, Jase and his 10-year-old sister Neive send a birthday card to their father James, who died in May 2014.
Ms Copland said: "He was overwhelmed and kept saying, 'My dad really got my letter mum'.
"I've always told Neive and Jase even if you can't get anyone a present, it's always nice to make sure you send a card at Christmas and birthdays.
"A small gesture of kindness can have such a fantastic impact on someone's life.
"Royal Mail actually took part and that gives me so much comfort."
