Here's a random story about my day:
I was walking to Wal-Mart for some batteries when it starting sprinkling outside. Not enough to be uncomfortable, but enough to darken the sidewalk. This made it impossible to tell the difference until my shoes were already sinking into the one random freshly poured spot. They only went in about half an inch and all of the concrete was gone by the time I got to the store. Then I bought some Hot Wheels and forgot my batteries and found a dollar in the parking lot. The end.
