50F, sprinkly; didn't feel beat but not nearly as zippy as yesterday

Oh yeah, on this one remote college campus road I take, came up on a minivan stopped in the center of the road. In addition to other causes for that sort of thing (pedestrians, baby ducks) I also looked to see if there was a cougar about to pounce (been some sightings recently). Negative all around, so I passed on his left (from behind him). Right then he started going, and moving toward me. I guess he decided we were in line and he wasn't yielding. But anyway I was going 20mph, way faster than him (and yet not nearly as fast as 'traffic' usually is on that road), so I just kept going and he continued putting up the left side of the road until I was gone.

Anyway, no event, just an odd interaction.
