*There are Two Doors, One is the Door of Truths and the other is the Door of lies, One will lead you to freedom and the other shall condemn you, You need only to figure out which door to enter, The Left or The Right, Two Guards Challenge you* Guard 1 R Door: Do not fall for His lies. Guard 2 L Door: Me a lier? Ok i see how it is, Traveler, The Right door would be the one you should take, Guard 1: See why would he not tell you to take his door?
