Carrondale Care Home, in Beaumont Drive, Carron, received a call from a member of the public who said their son had been thinking of others over the festive season and wanted to do something positive.
The facility was then sent a bundle of letters from the boy whose well wishes were warmly received.
All staff know is the youngster’s name is Adam.
Linda Stewart, the home’s health and well-being co-ordinator, said: “The residents were all so delighted to receive them.
“We would like to thank him for his kindness and thoughtfulness at this time of the year, especially during these challenging times.”
In October, Larbert High School pupils delivered much-needed cheer by writing lockdown letters to the home.
The S4 English pupils sent nearly 50 letters to give residents a boost while visits were limited due to the coronavirus pandemic.
