What's on your mind?

[Captain Wow]

So, let's suppose for a second that you are walking through your town center but you are unsure of exactly which direction your destination is, but you have a rough idea. So you approach the nearest person and ask them for directions, but they tell you to go in completely the opposite direction to where you think you need to be traveling. What do you do? Do you feel comfortable enough to say "sorry, you are wrong" considering you approached them for directions and would be reasonable to assume that you did this because you are unsure. Or maybe do you start going in the recommended direction?, then when the person turns around you run like hell back the other way?
