You're Under Arrest

We usually order our books at the library instead of browsing the racks.  I guess we do browse it is just on the on-line card catalog.  There were a couple of books at the library ready for us to pick up and today, when we were in town,  Dancer and I ran in and grabbed them quick while Dad and Spark waited in the car.  As we were coming out we could hear a siren of some emergency vehicle going off in the distance.  Dancer says right away, "Geez, we leave Dad and Spark alone for three minutes and they already got in trouble!"
