Suppose that comes down to the entity may know about you, but you may not know about it. I.e. you walk up to a Hotel one day and the security guard out front looks to you and says 'Mr. Hakim, we've been expecting you. Please, if you would proceed inside we will begin the extraction process shortly."
You then walk in, Diabolus a/e's you, and he then extracts your kidney, liver, and appendix.
