It is the power to summon the bus I need by walking away from the bus stop.
After my Caerphilly visit, I needed to catch Bus 26 back to Cardiff. After standing at the bus stop for forty minutes, I gave up, figured the Bus 26 runs different routes on Saturdays, and started walking to the next bus stop. When I was halfway between the two stops, I watched Bus 26 roll past. So I walked back to the original stop.
Fifteen minutes later I had to go to the bathroom, and I was just in the doorway of the Sainsbury’s when the next Bus 26 pulled up.
So I figured now I knew how far apart the buses were coming. I went to buy a brownie at the bakery down the street, and through the bakery window watched a third bus 26 pull up and then pull away.
Then I stood at the bus stop eating my brownie in the rain for an hour before the next 26 bus came.
