Some Kind of King Day?

During a time when students were having free play time, I overheard a conversation between two students. It went like this....

Student 1: "So why are we out of school on Monday?"

Student 2: " I don't know...I think it's some kind of king day."

Student 1: "But we don't have a king...we have a president."

Student 2: "I know, but I think we used to and he died or something so that's why we get out of school."

Oh dear...maybe we should have had our MLK lesson BEFORE the holiday instead of after!
