Court House - To a woman in a minivan who stopped in the middle of the road to pick up her child on busy Mechanic Street in front of the Court House library, directly blocking my entry into the parking spot I was in the middle of backing into: what were you thinking? Why the dirty look and mouth to me when you were at fault? Could we all please drive with safety in mind, think before doing something just because it's convenient without regard for others (including our own passengers), and treat others as we'd like to be treated?
