Another thing that theoretically COULD be trained is behavior

Some people just don't get it, they don't understand why they should or shouldn't act a certain way And it's okay, as long as they are willing to be coached But there are some principles that can't be taught, like loyalty, respect, honor, ethics If you hear a guy talking shit about his friends, do you think he won't talk behind your back? If he steals from someone, later down the line he will steal from you as well If he entertain his friend's gf after they broke up, soon as you break up he'll try to fuck your girl too These people can't be trusted neither changed, just avoid them
