BOSTON (CBS) – Maybe it’s the heat. Maybe it’s the trouble some of us are having trying to get a decent night’s sleep with the darn air conditioner sputtering away. Maybe it’s the economy.

Listen to Jon’s commentary:

Maybe it’s the Red Sox.

Maybe it’s all of the above, and more. But whatever the reason, doesn’t it feel like we’re in an especially foul mood these days?

Obviously, I’m generalizing. Someone, somewhere is whistling a happy tune, no doubt, most likely at the Raisman house in Needham.

But the signs of a nasty funk are everywhere, starting with the unbelievable behavior of that MBTA bus driver who allegedly decided to park her empty bus in a busy travel lane of Comm. Ave in Kenmore Square at the height of rush hour and eat her breakfast. Police say when a transit official came along and told her to move, she refused, then struck the official and damaged two other cars.

We haven’t heard the bus driver’s explanation yet, but I bet it’s a gem.

But that bizarre story isn’t so far removed from what I’ve been seeing on my commute. You’d think that clear skies and relatively light traffic during vacation season would lead to more relaxed behavior on the roads, but not around here.

To the clown who absolutely rocketed through the red light on Soldiers Field Road yesterday a little before 9 – yes, that was me screaming at you when we met at the next light a hundred yards further on.

The foul mood is reflected in current polling that shows 66-percent of us think the country’s headed in the wrong direction, a sentiment no doubt aggravated by the presidential campaign, which this week kept our friends at the fact-checking website Politifact busy.

In the last week alone, they’ve called Romney out for lying about the president’s position on welfare, and scorched the Obama campaign for trying to blame a woman’s death on Romney’s business practices.

Profiles in leadership, fellas.

But look – it’s Friday. A weekend of carefree relaxation lies ahead. By Monday, we’ll all be in a better mood.

As long as we don’t follow the Red Flops too closely.
