Don't Slam the Door

In Let it Go, the song from the movie Frozen, the lyrics go, "Turn away and slam the door." There is another part of the song that says, "Conceal don't feel".

I think these are unhelpful. Acting out anger is useless. Better to recognize anger for what it is and either stand back from it, or by recognizing that there's nothing to be angry about, get rid of it. One can acknowledge having anger without being controlled by it. Perfectly? Every time? All throughout one's life? No, but more often than not. And more so with practice. And the progress is completely worth the effort, even if perfection is not possible. 

It's also unhelpful generally, in my view, to conceal feelings. To some extent, yes. If destructive emotions are illusions, there is the danger that bringing them into the world functions as an act of validating them, or somehow makes the illusion larger, or stamps it with imaginary realness. Also, human beings are social, so by not concealing some emotions, one could pass them to another person, like giving them a cold. However, those specific concerns aside, concealing emotions as the main approach to one's emotional life seems wrongheaded. Physical illnesses aren't treated by ignoring their existence and pretending everything is fine. Likewise, destructive emotions probably won't go away by pretending that they aren't there or don't exist.
