Laputa In The Sky : Secrets Revelation

I fell deeply in love with this animation...
It was made by a very famous Japanese animator...The theme song was as nice as the story...Here it goes...
It all started with a girl, felling down from the sky, with a necklace, which glows and help her to float, a boy happen to pass by, and saw this girl which was floating all the way down...It was the stone around the neck that had this awesome power to help people float...
The boy held the girl in his arms, and put her on the floor...The scene was charming...The boy helped the girl to escape from the pirates that wanted the floating stone, and the authorities were looking for the stone also...Which the girl noticed that the stone may actually pointing the direction to the castle in the sky, which is Laputa, a legendary story that tells that this city is actually floating and flying, but, the residents from that city had long lost from the sky to be seen, and they were scattered around on Earth...
The couple's becoming friends with the pirates, and finally, they founded Laputa...And the girl which is actually the royal descendant from the Laputa kingdom, and she was the one to inherit the throne, which it was suppose to be...The girl was been held as hostage by one of the authority guy (also a descendant of Laputa), he planned to use Laputa for world domination (as all villains wanted), failed also in the end, due the boy's courage and the girl's willingness to destroy her own kingdom...Finally, they got out from the castle, and they saw Laputa (what is left of it), floating and floating, disappear within the clouds and from the eyes of the people...
 As the story ends, it wasn't too late to realize, certain secrets, it will be always forever safe, as time goes by, when the secret never been discovered by humans, the world might be safe from another disaster...As what I learn, certain secrets are better if you never ever discovered...People said that my mouth would always be the most tightest, no matter how I will never ever reveal your secret...And only dead people can keep secrets, because they were dead...
Not to say that I agree with the point of view that by only killing people, secrets will be kept forever, but, to urge for those people that keeping secrets, if you do not want others to make full use of your secret, don't bother to tell them, and who cares ???
Keeping secrets is like you are hiding tons of stone inside your heart, you can look for someone you trust to tell, or other ways that you favor to release...
For me, secrets are killing, and if I had a chance to know, or if I accidentally know it, that might be something interesting, as in, I wouldn't really care about it, even though curiosity drives me, but, to be honest and frank, I will try my best to stay myself out of it...Secret kills, and it creates conflict...Which I would try my best to minimize it even though it can't be escaped...
