This website is unfair cause I don’t know more than half of the words even though I’m “supposed” to know them. I don’t read a dictionary for a living so sorry if I’m not the smartest person in the world.
To be inconsiderate is to not care about another. Many people act this way because they do not understand why you cannot grasp a topic or have not learned about something yet. It is unhealthy to be inconsiderate.
