If you are a naive idealist you can feel all the paints of love and subtle pleasures of the unknown. Your soul is kind of opened to the future with all it's surprises. And there is a price. Disillusionment and feeling of betrayal.
If you are an experienced cynic or you already have been disillusioned once you loose the ability to see the world without distrust. You can no longer enjoy the subtle happiness and the most powerful joy doesn't reach your heart anymore. But you also can't be disillusioned and you don't have to suffer from betrayal.
Again, what's better?) To be closed in your own cocoon and be secured or live with the open heart until smth breaks it?
