A typical bucket with a bucket.
A couple of years ago, we were invited to the sub-Moscow water park. It was about 3.5 small. She whispered gladly (but loudly) from happiness. And suddenly some vanity among the servants of the aquapark, run there and there, mocking each other. About an hour and a half later, they approached us and tearfully asked the child not to whisper. It turns out, her whisper one-on-one whisper sound, which they call each other, if something happened" - it is they really hoped, unlucky apparently, that you will get to the fact that the loud sharp sounds in the performance of your child are not all pleasant. Then I decided to take a tactical approach. Good people, at least the reason invented.
