Yes, this is a vent. 

Goes to all those slow moving cows (SMCs) hogging the left lane on a two lane highway. I think these people, who just don’t budge no matter how long a tail they create behind them, are the most important reason why we have incidents of highway-rage. And the second reason: People stuck behind these SMCs who don’t HONK their freaking horns!

I have observed (especially here in the mid-west) people think it is improper and impolite to honk their horns at other vehicles, no matter how the person infront of you is driving. So if a slow moving vehicle happens to get infront of you, instead of HONKing the horn and letting the person know about your dissatisfaction about them hogging the left (and hence the fast) lane, people keep their anger bottled within and when they blow their corks off, follow the person to his (or her) house and confront him (or her) or take their guns to the highway and shoot. 

So here’s a plea, next time you see yourself stuck behind a slow moving cow, save a life and just freaking HONK your HORN !
