Strangers from around Minnesota flocked to a ten-year-old girl's birthday party, after several of her classmates didn't respond to their invitations, in hopes of giving her a celebration she'll never forget.

Mackenzie Moretter, who has a rare genetic disorder called Sotos Syndrome that has delayed her development, which makes it hard for her to socialize, told her parents she wanted a 'big-girl party' for her tenth birthday.

This meant inviting friends, but after her parents sent invitations to Mackenzie's classmates and heard no response, her mother Jenny Moretter took a different approach.

Jenny Moretter went on Facebook and posted in a few local groups asking families with girls around Mackenzie's age to stop by their Shakopee home on Saturday - and the response was overwhelming.

Mackenzie told KSMP that she is often by herself on the playground, saying that 'kids don't want to play me'.

Her mother said that kids seem to like Mackenzie, but they don't seem to socialize with her. But after not getting RSVPs and having families of Mackenzie's fourth-grade classmates cancel, she wanted to do something about it.

'I thought to myself, it is not going to happen again this year,' Jenny Moretter said about her daughter who was diagnosed with Sotos Syndrome when she was one year old, and her skull didn't form completely, causing brain damage.

She received an overwhelming large positive response and more than 700 people joined an event titled, 'Mackenzie's Birthday Party'
