Does anyone listen to z ro?

It's a metaphor. For keeping an eye on those closest to you since those are the usual ones that can cause the most damage. So when he says keep the left hand from knowing what the right hand did, he compared something that's obviously always close to each other like your "left and right hand". So his message is really dont trust anybody ESPECIALLY those closest to ya, so try and keep your "moves" to your self so there is not one person who knows EVERYTHING about you.
