After reading this whole thing I would have to congratulate you on the smashing of that guys mirror. Sometimes you need to let off some steam after a whole day of people trying to hit you in one way or another. Somedays however it is fun to just ride by and wave with a big dumb grin on your face. It all depends on how your feeling at the time.
However if I would have done the spitting onto the ambulance driver I don't think I would have stuck around to yell a bit more. I kind of think that the spitting or whatever action it may be as the period or exlamation point to the sentance.
BLAH BLAH BLAH BLAH BLAH
