A childhood belief about general

I had two bathrooms upstairs and one downstairs. One of the bathroom upstairs is directly above the one downstairs. Than I had the most brilliant idea ever!!! I ran upstairs into the bathroom and flushed the toilet. In, let's say, "mid-flush", I screamed nonsense words into the toilet. Than I sprinted down stairs and down the hall into the downstairs bathroom. I sat there, leaning over the toilet with the lid wide open, staring into the water. Waiting. For my voice.
