Usually when walking around at night I always encounter at least one car without headlights on. Today was 3 cars. Usually I try to shout headlights and point at their headlights, but sometimes the drivers have no clue what I'm talking about and they continue driving blissfully unware that their headlights aren't on. Today the first one didn't get it either, but she was at a stoplight and I yelled headlights 3 times before she got it. Second one was just passing me and I just shouted headlights once but then I saw his taillights come on after he passed me and the faint glow of his headlights. Third one was making a turn and I shouted headlights at him and he turned them on. Not sure why I even bother. Sometimes I never say a thing.
