You might not want to do this.

I forced myself, for a very long time, to almost never show a hint of negative emotion on my face due to the bias of those around me. Now, years later, I have a (wonderful) SO and a fantastic group of people around me who sometimes wonder why I'm so stoic to the point of almost being robotic. I'm not having to unlearn being so boxed up, and show those who love me what I'm feeling on my face.

Having emotions is not a bad thing.
