You want to get to your friends house and call him to get directions. He sounds persuasive on the phone and tells you where to go, where to turn etc. He tells you you`ll be there in about 30 minutes.
So, you drive and follow the careful notes you took when talking with your friend. Only, after an hour, when your finally at the end of those steps, you don`t see his house anywhere. Assuming that his instructions were fine, you take for granted that you took the wrong notes or turned at the wrong place somewhere.
So you call your friend again and he asks you where you are at now. So he gives you new directions to get to his house. You should be no more than 10 minutes away.
So, you drive and follow the direction and again, you land at the wrong spot. So you call your friend again! Assuming you are wrong and he is right!
This goes on for several hours until you finally realize he is making you drive around in circles!
Will you than say: I cannot doubt my friend. I started this journey with absolute trust and so, I must trust him now.
