There is an unusual way to measure the emotional cost of the coronavirus pandemic. It can be seen in letters to Santa Claus now arriving at a post office in southwest France. The post office answers mail sent to the traditional Father Christmas from around the world. Jim, from Taiwan, put a face mask inside the letter he sent to Santa Claus and wrote “I heart u.” Alina, 5, asked in her letter that Santa please use the front door because the back door is only used by Grandma and Grandpa to lower their risk of catching the new coronavirus. And 10-year-old Lola wrote that she is wishing “that my aunt never has cancer again and that this virus no longer exists.” “My mother is a care-giver and sometimes I am scared for her,” Lola explained. She ended with “take care of yourself Father Christmas, and of the Elves.” The letters arrive by the tens of thousands. They show what children are thinking about this Christmas season after a year of illness and financial difficulties.
