In 3rd grade (age 8/9) I thought that if I burped/talked/yelled/hocked loogies with my mouth closed that nobody could hear me. I'd sit there and openly yell at people right in front of them! When people told me to stop burping (I'd just learned to swallow air!) I was legitimately dumbfounded that they could hear me!
