Bullies have always been around. There is really no way to get rid of them. Don't bother asking why, it's just something in their DNA.
In grade school, a bunch of them gang up on smaller, weaker kids and forcibly take their lunch money. As teenagers (or older), they
pile into a car owned by one of them and harass cyclists, joggers, and elderly people walking their dogs. Yes, I have seen
all of this. Sometimes, they are stirred up by the rantings of the brain stems on talk radio. I don't think anyone can
deny this. Funny how these so-called "shock jocks" are so brave with their mouths, while inside high-security office
buildings, isn't it?

I had eggs thrown at me, years ago. One connected, and gave me slight cuts on my left leg. Other incidents: A beer bottle,
(Domestic lite brand, of course) a bag of McDonald's garbage, and something made of plastic I could not identify. None of
these objects connected. On one occasion, on a morning commute, some rocket scientist leaned way out of the passenger
window of a passing Honda, and hurled a cup of Dunkin Donuts coffee at me. They failed to work the prevailing headwind
into their calculations, and the coffee made an arc, landing on the rear quarter and trunk lid of the car. Oops.

I have noticed much less of this in Eastern MA, during the last few years. ( Before anyone mentions it, yes, I am aware
of the recent incident, involving
a member of the MA state police. ) So, the number of bullies are diminishing. I would say time is doing its job.

Bullies are bullies, and there is little to be done with them. I would definitely report an actual assault, should that happen, but
there is nothing to be done about the usual yelling. The best thing is to hope that sooner or later, what goes around comes around.
Sometimes, it does.
