I am sure you've all seen it before. You're on a hike, and you come across a mud puddle. There is plenty of space on the side of the trail to pass by without stepping in the mud. But, for some reason there are adult sized footprints right down the middle of the mud puddle. So my question is: what kind of person is walking through mud? Is it intentional or are they just stupid and/or unaware of their surroundings?
