Heading through the Meadows, I'm approaching a mother and child in the cycle lane ahead and cast a glance over my shoulder. There's a big green transit van catching me up so I slow behind the other cyclists and sit up to pass when safe.
Except I become aware of the van also slowing, and look again to see he's 5 yards behind and letting me out to pass. He then didn't pass as we approached a pedestrian crossing, which we both stopped at for the red, then let me go ahead (clearly seeing that up ahead the traffic was such that passing would have involved getting too close, and he would have to stop for a queue).
And just when we were thinking of getting a plumber to come and give us a quote for a new bathroom...
