Extreme Road Rage

As I was running a couple of errands with Addy today, I encountered a woman who I'm pretty sure was mental! We're driving along and we came to a 4-way stop. I must say that the placement for this stop is very inconvenient, because it's really close to a light. I was sitting at the stop sign waiting to go straight through the light. The problem was that even though it was my turn to go, I couldn't because the light was red and if I went through I would have blocked the whole intersection. The lady that I mentioned earlier (who also happened to be quite scary looking!) pulled up to the same 4-way stop to the right of me and was in the same predicament I was, but I'd been waiting at the stop sign for much longer than her. So finally the light turns green and we're all able to go through the stop sign. So I have the right of way, right? Apparently crazy lady to my right didn't think so. She goes on ahead through the stop sign and I honk at her. I don't honk for a long time, just a brief, polite honk. I guess that was enough to set her off, because she stops right in the middle of the intersection, rolls her window down and starts making somewhat dramatic hand gestures and mouthing words at me. Who knows what she was saying and who really cares, but I'm pretty sure she mouthed the b word in my direction at least 3 times. My reaction was simply wave at her to move her crazy self along and laugh out loud. I can understand the whole road rage issue, because I've been there. But this lady looked like one of those people who might own a gun and use it on me at any second and for something that she was in the wrong for. Truly unbelievable!
