"I know this might be something silly to rant about, but my heart is breaking for my son. We invited his whole class (16 kids) over for his 6th birthday party today. Not one kid came," she posted.
And when other group members saw the post they sent Buratti messages asking if they could bring their own kids to Glenn's party to celebrate.
The message even reached staff from the Osceola County Sheriff's Office, who asked for the family's address and said a helicopter would fly over their St. Cloud home.
The helicopter came to the house within an hour, and the pilot flew low enough that Glenn could see him waving.
Glenn, who loves public safety and law enforcement, was overjoyed with the party, and his mom said that though he is usually shy, he took to his new friends like he'd known them all his life.
"In general, deputies have big hearts - they thought about their own kids and wanted to make this boy happy because it was such a sad situation," Buratti told Today.
In total, about 15 kids and 25 adults showed up to celebrate and eat cake, give gifts to Glenn and play in a bounce house.
One woman brought the birthday boy a bike, while others brought toys. Buratti said one man came to the party with a camera and took pictures he later gave to the family.
"It was just amazing. The people who came out were so awesome," Buratti told the Osceola News-Gazette.
And Glenn's birthday celebration didn't end on Sunday - several crews from the Sheriff's Office and Osceola County Fire Rescue stopped by the family's home on Wednesday.
Though Buratti knew the crews were coming, she left it a surprise for her son to see as they were on their way home from school.
"We got to the stop sign by our house and Glenn was like, 'The fire truck's at our house!' I said, 'It's okay, they're there to tell you happy birthday,'" Buratti told CBS News.
They all wished him a happy birthday, gave him tours of their fire truck, squad cars, motorcycles and a SWAT vehicle and showered him with more gifts.
"And to think, all this happened because nobody showed up to his birthday," Buratti wrote online. "Thank you, thank you, thank you."
