Tobirama was walking to the Hokage's office to ask Hashirama something, but when he entered the office he saw...

....Hashirama, a bunch of unsorted documents around him and he was launching paper airplanes out of paper

Tobirama's eyes widened a little, he was a little surprised by what he was seeing, but he wouldn't be too surprised about that, it was still his brother. And that wasn't really the strangest thing he had seen in his life what could his older brother do.

"Are you having fun..?"

He said with some sarcasm as he watched him toss another paper plane.
