A make-believe game leads to suspension for one Colorado second grader.

And, the suspension is something neither the child nor his parents understand.

Seven year old Alex Evans doesn't understand his suspension.

He was playing the game during recess at Loveland’s Mary Blair Elementary School, and threw an imaginary grenade into a box with pretend evil forces inside.

He did not throw anything real or make any threats against anyone.

He explains he was pretending to be the hero.

But his imaginary play broke the real rules.

The school lists what it calls absolutes under the parent resources section of its website.

Absolutely no fighting, real or imaginary. No weapons, Real or imaginary.

Alex is like a lot of second graders... Perpetual motion.

And his mom says he doesn't understand why pretending to be a solider is wrong. "I think that when a child's trying to save the world I don't think he should be punished for it." Mandie Watkins says.
