Yes, it is a big world, but it can be a lot smaller than you would think. I come from a small town that in the 2010 census had 1342 people.

When I was stationed in the Philippines I was walking out the front door of the hospital one day and a guy from a town 15 miles away the in the 2010 census had 1852 people was walking in the front door. Yes, I knew him.
