It's not about how physically strong you are but how useful you are towards other people.
"I am useful to the Cruz family for I give them source of income through the fruits I bear.Also, I sustain them with Vitamin C which is good for their eyes."
"I am the strongest among all of you! I still stand no matter how strong the storm is.They can use me in building their houses."
"I may not the strongest tree physically but I die usefully.They can sell and ate my fruits.They can use my shell in making accessories and use my husk for burning fire.Out of my leaves, they can make hanging rice and produce broomsticks. And cut my body for building their houses."
"Hahahaha, you have nothing against with me! I am your national tree.I am the most expensive for I am the strongest and the most useful.They used me in making furniture and big houses."
In the land of Nerva, there lived a family who are loving and contented. Their source of income are the trees that surround the area.
One day, the trees argued who among them is the strongest and the most useful to the Cruz family.
