I don't know why, but it's happened to me FOUR times this week:
I pull up to a stop light, I'm two or three cars back from the red light. Inevitably someone, this week all women, becomes comatose or starts playing with their "stupid phone" in front of me. The light changes and they don't notice. Result is that twice I've had to sit thru another left turn red light. Most recently, yesterday on my way home from work, I was going straight and the woman in front of me did the same thing; since I was right behind her, I blew my anemic horn. She jumped like I'd shot her and took off. Why the hell can't cagers sit thru a light without falling asleep or amusing themselves with some damned electronic device??
I came into this world kicking, crying and covered in someone else's blood. I have no problem leaving the same way.
