Sifu's Son Can Hear and Talk with My Tortoises

Last Sunday, Sifu came to my house.
He brought his son along.
His son saw my tortoises and play with them (still in aquarium).
Then Sifu said that he heard his son talking with my tortoises 
And my tortoises had sound came out.
Not only once, is three times.
Sifu plays a joke "Your tortoises become fairies."
Why my tortoises don't talk with me?
I'm their owner ah.
My father is also their owner, 
but my tortoises also no talk with my father.
I think maybe Sifu's son has a special talent which can communicate with animals.
I want to have too.
But I think if I have, I definitely will scream and become crazy 
when the animals such as tiger and lion talk with me.
It will be horrible to my whole life.
But if I can only communicate with my tortoises, 
not with other animals, then I will be more happy.
Because I can know my tortoises' needs.
