A person who eats ripe fruits partly eaten by birds becomes talkative.

Dr Abe V Rotor

Guyabano (Anona muricata) partly eaten by fruit bat during the night.

This is a cure to children who are just too quiet for their age.

The old folks would give children ripe fruits they first offer to a parakeet or parrot. At one time I tasted guayabano ripen on the tree which bore teeth marks. Since then I began reciting in class.  

That’s how convincing Lolo Vicente was. But the pitch of my voice was unusually high. It was a fruit bat that tasted the guyabano fruit, and early sunrise must have prevented the nocturnal animal from finishing it.  

By the way, birds and bats may carry certain diseases, such as rabies and bird flu.~
