ADHD or just an @##-Hole

One characteristic of ADHD People is Irritability. This is my biggest struggle. I am impatient and I have said before the trouble with the earth is its inhabitants. It is usually strangers who give me the most aggravation. They are completely unaware what is going through my mind. When I see their buffoonery in the way that they drive their cars or complain about shit out loud, I have nothing but contempt for them and the air they breathe. I feel as a hostage when I am not able to get away from them. I believe that is my ADHD and while medication keeps it at bay, it is still difficult for me and many ADHD people to just blow off and dismiss.   Perhaps many of these people are ADHD. Does that matter while I am being aggravated?
