Why can one rude idiot ruin your day?

It always seems to happen this way, at least for me. One rude stranger will do something and make me mad, and I just can't shake it. It puts me in a bad mood and I can't forget it. I try so hard to be considerate to other people, so when someone else is blatantly inconsiderate to me, it really gets to me.

The other day I was driving. Yeah....people always seem to be at their worst when driving. So, right near my house is a section of road, a main road, where the two lanes go down to one. Now for some odd reason, the left lane must merge in. There is a sign that clearly shows the right lane goes straight an the left lane ends...they must merge in. I always get in the right lane so I never have to worry about merging. Well, the other day, this idiot is in the left lane and as the lanes merged together, he was kinda next to me but behind and blared his horn at me, like I was in the wrong. This isn't the first time someone has beeped at me in this situation, but clearly, as the sign shows, they are in the wrong, not me. So badly I want to slam on my brakes and get out, point at the sign and show them they are wrong.

But I tried to shake it off and just continue on. I had to go to the pharmacy to pick up a prescription-- it was a few blocks down. I put my right blinker on, in plenty of time, and know what the idiot does?? As I slow and make my turn, he lays on his horn again.

Why? Why are there so many people out there who insist on being rude and mean and just down right nasty?? The merging thing, yeah, whatever. A lot of people make the mistake there...it is odd for a left lane to have to merge into a right. But the blaring of the horn as I made my turn...that was completely unnecessary. Did it make him feel good in his big black 4x4 to beep his horn at little ole' me in my car with my kids?

Mean people really do suck.
