You, and your girlfriend find a crossroad in the middle of the road, as you see a sign pole that had 4 arrow shaped signs attached to it, explaining which path leads to where. The problem was, you didn't know where to go, because the signs were giving you both mixed choices to which direction you would select.
"Well I'm completely stumped," You say. "We're lost in the forest, and we need to find a way out, and fast." "Well maybe the signs here, can help us," your girlfriend explains. "Either that, or we can go back the same way we came," You say, and turn around, only to find that the fifth path you went down vanished. "Never mind we'll try one of these signs, and see where to go." "Perfect, now as we can see from the sign, there are 4 ways we could go in the forest," your girlfriend says.
"So, which way do you think we should go?" You ask. "I don't know," your girlfriend answers. "I guess since the other path vanished, these will have to choose a path, and hope for the best." You then see your girlfriend go down one of the path's, and follow her.
