Myself: my sweet little brother, what the hell were you doing with your friends?
Brother: my friends instigated me to smoke. Sorry, I will not do so anymore.
Myself: you must give up the bad company.
Brother: okay, I will do so.
Myself: by smoking cigarettes, you were going to destroy your life.
Brother: Actually, I do not know the bad effect of smoking.
Myself: smoking causes different fatal diseases like cancer, asthma, bronchitis; blood pressure etc. besides, it harms not only you but also others who are non-smoking.
Brother: oh my god; I will never do so.
Myself: thank you
Brother: same to you.
