Context: To make things worse , as I tried to drive up MY DRIVEWAY , a family of mouth - breathers got in my way . The 5-year - old boy apparently had more intelligence than all the others combined , as he knew to move to the side and wait . Too bad his dumb - as - rocks mom and sister just sort of stood there oblivious to the car in front of them . Eventually , they noticed , stared at me a while , then started slowly moving along .

Answer:
