You are stranded in a land with only two big cities. Knightville is populated only by Knights, and Liarville - only by liars. Naturally, you wish to get to Knightville, where you hope to find help.

During your travels, you meet a resident of these parts, who must have come from one of the two cities, but you do not know which.

With one simple question, how do you find out what direction Knightville lies in?

The resident you meet could be a Liar or a Knight.
If you ask him where do you live?
If he is a Liar (Living in Liarville)
He will point to Knightville (which is a lie!)
If he is a Knight (Living in Knightville)
He will point to Knightville (which is true)
So Either way you get to Knightville!
