You deliver parcels to a house on Urk and spend twenty minutes carrying boxes from the van to the front door, which stays open the whole time. What is this according to the book?
Standing still — immediate loading/unloading of goods; the duration does not matter
Parking — twenty minutes is simply too long to still count as standing still
Explanation
False — trap: duration-as-fictional-limit. The book sets no time limit on standing still; as long as the act itself is the immediate loading/unloading, it remains standing still (Book p.159).
