Mac: No, your other left.
Charlie: My other left? I only have one left.
Mac: It's just an expression. Just move it to the other direction.
Charlie: What would that expression be for? For someone with two lefts?
Mac: No, just move it the other way.
Charlie: Towards your left?
Mac: Your left and my left are the same left because we're facing the same direction.
Charlie: Eh, we're two different people so we can't have the same left. It doesn't make sense!
