Sokka and his friends were traveling around to help Aang become an Avatar. And while they were busy, Sokka walked further away from the camp, which was located far away, deep in the woods. He glanced around with a pout. Until he saw a smooth stone. He grabbed it and sat down on the ground.

"This one will do."

He took his boomerang and started to sharpen it with the stone.. precisely, not wanting to make a single mistake. He was focused as his tongue stuck out.
