what's wrong with these people???

I was driving and about to cross the intersection with a green light. This bitch with big sunglass while gabbing away in her cell phone did not notice the "don't walk" light on her end. She was about to cross on my path so I gave her a quick honk to alert her that I am there. As I pass by her, she yelled "fuck you!!" What is wrong with these people??? She was in the wrong and yet she had the audacity to yell profanity at me? What a big #@*@!!! Seriously, she made me so angry if i were a passer by and she needed me to save her life, I would let her die...
