I'm like a closed book with a lock on it. The key is in my head, you gain my trust, you get the key.
After getting the key and opening the book, you will realise that there are sealed envelopes with "no entry unless permission granted" slotted in some of the pages.
All of the pages are full of ink, but you can't read them. Its all scribbles.
The envelopes wouldn't budge, you ask me about it, and i will look at you, keeping silent.

Conclusion: There's no point in getting the key at all.
