Good morning to me

So this morning, on my way to work, this guy has his blinker on to get in the right lane, and I did not let him over because he was slow. His retaliation? To get behind me and put his brights on. Which really pissed me off. So he's mad, now I'm mad, and he's right behind me with his damn brights in my eyes. So I hit the brakes to make him mad...not the best solution, but come on! What is with the brights in my eyes???? People are a**holes. I'm sure he thinks I'm an a**hole, but there is nothing worse than being stuck behind a slow van. That's the start to my morning, it can only go up, right...? I hate people in traffic. A lot.
