It seems like viral birthday parties are officially a thing, and we could NOT be happier about it. Last month, we were wishing Odin Camus a happy birthday after he got the party of his life thanks to the Internet, and now, we’re a little misty-eyed over Mackenzie Moretter’s 10th birthday bash, which took place yesterday and totally ROCKED any other 10th birthday party we’ve ever heard of.

Mackenzie, who is from Shakopee, Minnesota, invited 10 girls to her birthday party . . . but not a single one said they could come. “She’s never really had any friends,” Mackenzie’s father, Matt Moretter, told BuzzFeed News. “No one has ever really come over to play. She’s just kind of played with her brother and sister’s friends.”

(PS here’s a pic of Mackenzie and her parents speaking with Fox Atlanta.)

Mackenzie suffers from Sotos syndrome, a rare genetic disorder that damaged her brain and made socializing with others a difficult process. It has also caused gigantism, making Mackenzie much taller than her other classmates, according to USA Today. “Kids don’t want to play with me,” Mackenzie told Fox Atlanta (effectively shattering our hearts).

But her mother, Jenny Moretter, wasn’t having it. “I thought to myself, that’s not gonna happen again to my daughter this year,” Jenny told Fox Atlanta.

So she took to Facebook, asking mothers to bring their daughters to Mackenzie’s party. “My daughter has Sotos Syndrome which means she has development delays such as speech and learning,” Jenny wrote in her plea. “At school she struggles and is often alone on the playground. As a mother, it is heartbreaking because you want your children to be happy. I’m reaching out to moms who have daughters between the age of 9-11 that would love to come to a birthday party tomorrow from 11-1:30. You don’t have to bring gifts or stay long, just stop by and wish her a happy birthday.”

Jenny expected maybe 10 to 15 people to attend . . . but she had NO idea what the Internet had in store for the Moretter family. Mackenzie’s story attracted the attention of local news outlets, and within an hour, she had hundreds of RSVPs on the Facebook event page.

An estimated 300 people attended Mackenzie’s big bash. “It was amazing,” Matt told BuzzFeed News. “There were so many people who had similar stories to ours that we got to meet.”

She also got an amazing Frozen birthday cake (girl’s got great taste!):

In fact, she even became necklace BFFs with Elsa herself:
