Last summer my brother and I stayed for a week with some friends in Boston. That was our first trip away from home. One morning my brother said that he wanted to visit a famous church. We started out but we did not know which way to go, so we stopped a stranger and asked, "Excuse me, does this street lead to the Old Church?"
"Yes, you're right," he replied. "Just go three blocks and turn to your left," he said. "You can't miss it."
So we walked three blocks and turned to our left, but the church wasn't there. We then asked a second stranger. He said, "Go three blocks and turn to your left. You can't miss it."
But again we couldn't find the church. Finally we asked a third stranger. Again he said the same thing.
This time we found the church, but we wondered if everything in Boston was three blocks and a left turn away. Just then somebody walked over to us and said, "Excuse me, where is the nearest post office? Can you tell me?"
"Go three blocks and turn to your left," my brother replied, "You can't miss it."
