Bill Gates revealed as Reddit user's Secret Santa

 Reddit user Calid7, identified by her first name Cali, was shocked when her Secret Santa on the site turned out to be billionaire and philanthropist Bill Gates.
Cali received a Loki helmet she listed as her "pie in the sky wish," a book of gorgeous pictures of her bucket-list destination, Africa, a stuffed polio virus microbe, and a donation in her name to Shot@Life, a program that facilitates vaccinations for children in poor countries.
"Melinda and I have been to Africa many times and loved it. I hope you get a chance to visit and check that off your bucket list. Merry Christmas, Bill Gates," he wrote in a note with the gift.
Cali shared her joy on Reddit.
"I can not believe it. I am literally shaking right now I AM IN SHOCK (someone get me a blanket!)," she wrote.
Last year, Gates gifted a stuffed cow to a Reddit user named Rachel to represent the real cow he donated in her name to Heifer International and a travel book from National Geographic.
