After receiving a large FedEx box Friday morning, Aerrix opened it, peeled back the bubble wrap, and was greeted with a photo of none other than mastermind behind Microsoft. Aeerix immediately called her husband, a programmer, at work.

“Bill Gates is my freakin Santa!” Aerrix wrote in a Reddit post.

Gates included handwritten notes and several photos in the package, included a framed photo of Aerrix and her husband with Gates Photoshopped in.

In a letter, Gates wrote:

Dear Aerrix,

I can’t believe your Secret Santa left you hanging last year. To ensure you don’t lose faith in the Reddit community, I’ve enclosed several gifts that I hope you will enjoy. There are a few video games for you to play, some things to keep you warm, and three of my favorite movies for you to watch over the holidays.

I’ve also made a donation in your name to, to help give more students the chance to learn computer science.

With best wishes from Seattle,

Bill Gates

P.S. I wasn’t able to consult with the Sorting Hat, but I can tell you are quite clever – so I got you a pair of Ravenclaw slippers from Hot Topic.

Gates included a Cajun cookbook so Aerrix could channel her Louisiana roots, and a few gaming essentials: an NES Classic Edition, wireless XBOX One controllers, and XBOX One Minecraft edition (Attached note: “I love my XBOX and thought you might like one too” – Bill). There was also a Zelda tie blanket.

“I’m just blown away by his generosity,” Aerrix wrote.
