It can be so hard to shop for some people during the holiday season, especially kids, who always want the latest video games, movies, and toys.
This year, a boy in Blaine, Washington, made a peculiar request and now he's getting dozens of gifts daily from people he's never even met.
Twelve-year-old William Thomas' Christmas list always included the usual stuff, like Blu-ray discs, art supplies, and snacks.
It doesn't take much to make him smile.
Take for example the stroll he and his teacher take each afternoon, from his classroom at Blaine Elementary to the district office, where he drops off mail.
"He gets really excited," explained his teacher Aime Nadeau.
It's pretty much the highlight of his day and sometimes it's the best part of his week.
William doesn't get invited to sleepovers, play-dates, or birthday parties, and to be honest, his mom Kay isn't even sure her son would be able to handle any of that.
"When people first see him I see the stares and I see the curiosity and you want to know, you want to know what's happening," she said.
That's autism. William doesn't speak, so he signs or writes most of his thoughts. It's how he communicates, and it might explain why this year he wants something different under the tree – mail.
But his mom couldn't possibly make it happen on her own.
"I have never done or asked for anything like this before but I felt the need to, the need that comes from being a mom and wanting to do everything in your power to make your child happy," she wrote in a Facebook post a few days before Thanksgiving, requesting that family and friends send William a card or letter.
Within a few days, her post was shared by thousands, including the organization Autism Speaks.
"We got about 1400 likes in a few hours," said Kay Thomas.
Now William is getting mail from all across the country. One letter just arrived from Northern Ireland. Many of the envelopes are from people he's never met.
"I can't even describe it, everybody is loving your child and seeing him the way that you want them to see him," said Kay.
She's trying to save the boxes of letters for Christmas, but she's letting William open a few each day, because he's just so excited to get notes from all those people.
"They just want to be able to make him happy," she said.
