I jump up and down and scream from the top of my lungs. Why is screaming ever so loud can be said as screaming from top of "" lungs? Is screaming low doing it under my lungs? How do you scream low? I remembered when I had laryngitis, I got really upset I kept screaming and screaming and screaming, that was very awesome, coz I was screaming quietly, everybody thought I was very polite.
