What's going on?

Kranji, 55 km. Situation 1: bike shop moves, a pet shop eventually takes its place. Bike shop moves again, another pet shop takes its place. Video shop closes ... and a pet shop takes its place. Coincidence? Situation 2: someone is afraid and to avoid the situation wants to go into a more fearful situation. But is the current situation so fearful when there is much data including first hand experience that says it isn't? Is the other situation less fearful when there is so little data, not even first hand experience? Situation 3: there's a strange sound after I cycle through some undergrowth. I look down and see nothing stuck on my drive train or frame, but still hear something. I'm tempted to ignore the sound but ignoring it doesn't make it go away. I stop for a closer look. A cable has somehow worked itself loose and is rubbing against a tyre. There no friction without sound, no smoke without fire. If it's not desirable or possible to avoid or to change a situation despite best effort, then the only thing left is to accept the situation and change ... me.
