One of the biggest issues I have with people is rudeness. It is a very poor reflection of one's upbringing to possess this awful quality. Being rude is appropriate in very specific, called-for situations but in most, can inhibit one's success, one's character, and one's ability to be relatable and make good, strong connections in their life. I can plainy say: "don't be rude" but I truly have come to understand knowing your place and when not to be rude comes with the rebuilding of one's character and relearning manners, if they ever had any to begin.
