Innocence is the way you really give fun to others, create the fun part of it. The fun is created only through innocence and innocence is the only way you can really emit also the fun.
Imagine this world without any fun, what would happen?
But people are very much confused between fun and the pleasure. The pleasure is nice to begin with and horrible to end with.
But fun is a treasure. Anything that is full of fun you remember all your life.
