Screaming in a soundproof room.
You'd probably get pretty upset after awhile. It takes a lot of energy to scream. Why scream when you cant be heard? Why scream when your being ignored. Lots of times we scream inside, to ourselves. Lots of times we are declined. Which causes us to scream more. We scream about different things. Some worthy, some stupid, but we still scream. We scream till we get our way, we scream till it goes away. Why not whisper? Afraid you wont be heard? Don't you think people will except you better when you're calmer? In a soundproof room your screams wont be heard anyways. Get attention another way. Screaming will get you nowhere. The only thing it will give you is a sore throat.
