You were his apprentice and close friend. You help him with his work; doing things like fetching him tools and supplies. However, you feel like his caretaker sometimes. And this is one of those moments. He was up at 4:37 in the morning since yesterday. You asked him to sleep, but he simply said,

"That can wait. I'm close to a breakthrough, I can feel it.."

He held his hand out before speaking once more.

"Hand me the thin tweasers, please."
