Incidentally… 
I've been cycling around or about 70 years now. But it's only in the last couple of years that people in cars, and to an extent people walking, have become really horrible to me.
Now, as I cycle along, people in cars jab their fingers to the side of the road, incorrectly telling me that this is where I should be cycling.

People drive too close to me if I'm wearing a helmet (unless, oddly, I'm carrying visible greenery or flowers on the back). If I *don't wear a helmet, my grey locks are no impediment to their impertinence in lecturing me about why I should.
Where did this nasty enmity come from?
