A young boy taught his grandpa that "you can dance anywhere" so long as you use your imagination.

Kyu San Juan, a five-year-old from Wisconsin, was born with cerebral arteriovenous malformation (AVM), an abnormal connection between the arteries and veins in the brain. He went undiagnosed with AVM until it ruptured in 2017, causing Kyu to suffer a seizure and become incapacitated, according to his Facebook fundraising page.

In 2018, Kyu had a craniotomy AVM resection performed, but after his one-year post-op check, the doctors informed his family that the AVM grew back. He needed to have surgery again. The night before his surgery, scheduled on June 5, Kyu and his mother took his grandfather to a Green Bay grocery store for an impromptu dance party, and captured the adorable moment on video.

At 11:57 p.m., Kyu's mother drove him and his grandpa, Txhiaj Sawm Muas, to Festival Foods. "Do you guys need to buy something?" Kyu's grandfather asked. When Kyu told him they were going to dance in the grocery store, he said, "Here? People are going to think we're crazy! I thought we were going to a party or a club."

According to Kyu's mother's Facebook post, Kyu responded, "Grandpa, [use] your imagination. You can dance anywhere!"

"Thanks dad for being such a good sport for Kyu and giving him all of your time before his surgery tomorrow. It was pretty fun!" Kyu's mom shared.

"The surgery went well and better than what the doctors had anticipated," his mother shared on Facebook. "Thank you everyone for your concerns, support and prayers. We love you all so much! Mark and I truly appreciate your love for our son."
