I used to clench my fist, by keeping my thumb inside the 4 fingers. Buddesh de Silva actually corrected me.

I still remember because I used to always only ever make a fist that way. I dunno. That was just how it is. BUT it's wrong.

He was like, oh you gotta, keep the thumb outside, and corrected me.

As a reward, I forgive him for carrying me once, because I'm too skinny.
