wow good one if they are not barking then they can't bite sorry not to sure about this
When I was younger I loved turtles. I learned to be gentle with them and it helped me realize how we needed to care for the environment. It helped me to be more understanding of why we should always care for others with live.
The second one. To protects them from hearing the deadly song of the sirens
Society would be very chaotic and full of mistrust as people will say things they didn’t mean to say. It is human nature to protect and not reveal certain thoughts.
Hope this helped!
