Choosing to suppress emotions is not logical, it’s emotional. Usually fear & shame. It is so scary to feel, so the only thing to do is disconnect. Logic is recognizing that a hurtful event hurts, therefore tears.
Logic means understanding and considering all variables in an equation, ignoring or devaluing a variable such as emotionally, therefore cannot be logical because you do not have the full equation.
I encourage you to reassess your definition of logic, the hemispheres and all the other different parts of the brain do not live in isolation of each other. As an organ, the brain itself cannot ignore it's own variables, you may just think you can.
I will see you, in class!
