There is a fine line between ignorance and inconsideration. Sometimes it is difficult to classify someone’s behavior as either ignorant or inconsiderate. The similarity leaves me wondering most often while driving in traffic. For instance when I pass someone on the expressway, that driver may suddenly pull over into my lane to pass the car in front of him. Is the other driver ignorant of the situation because he did not check whether the passing lane was clear? Or is he simply inconsiderate because he wants to pass, no matter if there’s another car already passing him?
By definition, ignorant can mean unaware or uninformed, while inconsiderate can mean heedless or thoughtless. I guess someone can be unaware of something because he is thoughtless. Therefore someone can be ignorant because he is inconsiderate.
