I'd tell my child; "why would you want to be like me, when I've raised you well to be even better, Are we not gods; created by the greater God, as greatest is what we are. You'd seek perfection, but being a better version of yesterday self, is what you'll find"
I'd tell my child; "promise me you won't fight as long, to become the ones we've fought against. There are no true successors to war; if the Dead are the only to know it's end. I'd best fight those battles long before you do.
I'd tell my child; "the world will beat you up, long before you learn how to fight. A lover seems weak in their eyes, but they're just weaker to love"
I'd tell my child; "no effort is worth the effort without it's due. Working yourself to death for another's livelihood, seems like the slavery of old in modern times"
I'd tell you child many things, but still there are many things I'm yet to learn and discover. As much as I can teach, I learn a lot from you. I only became a father, after I became a father to you.
