I, too, sometimes ride like a jerk when I'm late. I admit this not to excuse you, but to condemn us both as human and prone to error. Lucky, being human also makes us capable of learning from our errors. So try not to be late, and when you are, don't take it out on peds.

The honker behind you was actually doing you a service, I think. If no one called you out for cutting through the 'walk, you might've felt that you'd gotten away with it, which might positively reinforce the behavior of violating someone else's right of way for your own selfish desire to get to work on time. Publicly shaming you will hopefully have the opposite effect.

Pacing you for three blocks is a bit excessive, though. Perhaps he felt that you didn't get the message and thought that his horn, if sounded for long enough, would develop from a monotone bleat into a nuanced denunciation of your inconsiderate behavior? If only there were someway to let the honker know that you understand, you're sorry, and now you both may get on with your lives without further confrontation.

Or maybe the honker, while right to chastise, is just a sanctimonious jerk who really enjoys pointing out the wrongs of others and so revels in the righteous anger of shaming wrongdoers that he cannot stop even after the shaming has accomplished what it needed to. In which case, **** him for being an error prone human.

Mmmm, delicious circularity.
