You know the type. He or she is going to teach you a lesson. What sort of lesson? Often, a lesson related to traffic, as in demonstrating by position or speed that pedestrians or other drivers should exercise more care in turning, or in moving, or stopping, or slowing, or speeding, or hogging the road, or not signaling, or not walking on the sidewalk, or littering. Et cetera.
That type is me.
Mea culpa, mea maxima culpa.
(What's my penance after this confession?)
(Naturally, such "life lessons" never result in the desired changed behavior, right?)
