It's called "Buddy Day" and it certainly is a big day for special needs students at Heartwood School in Mason.
That's when students from Mason High School come to Heartwood and pair up with students for the entire day.
The pairs do all kinds of activities including swimming and making ornaments.
The founder of the program, Andrew Chapin, said the day is always a surprise, because many of his students do more learning than teaching.
"Really today the roles are reversed," Chapin said, "It's the Heartwood students who are teaching the Mason students some valuable life lessons."
Faculty from both schools said they hope the tradition will continue for many years to come.
