Reiji shook his head. what the hell am I doing? He thought. He took a piece of paper and began writing.
Mother,
I've left for a short while to train. I will still come by to see you, but I assure you I'm fine. Those weapons you acquired, the guns... Learn to use them. Trust me, you'll need to. The humans have created a gun that can slash right through a mountain, using the same energy I can use. So please, swallow your pride and use the guns. For your sake and our species.
Your loving son,
Reiji
When he was finished writing, he went back in the grate and closed it as quietly as possible. "It's done." He said.
