Throughout life people will make you mad, disrespect you and treat you bad. Let God deal with the things they do, cause hate in your heart will consume you too.
There are many people in life who don't understand what good really is, and probably never will. This is caused by a plethora of ideals and beliefs, but the underlying factor usually seems to be that a person of this nature simply cannot figure out how to love people, including themselves. When we encounter people who live this way, we must know that the problem doesn't lie within our relationship with them; the problem lies in them not being able to love themselves.
