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 .

Possible answers:
(1). They have a difficult time reacting quickly to situations , and were moving slowly for this reason.
(2). None of the above choices ..
(3). They are vision impaired and had no idea whatsoever that they were potentially in harms ways.
(4). They have a death wish , and were optimistic that the car may hit them , as they hope.
Q: What led the mother and sister to refuse to move when they saw the car coming towards them ?
(1).
