(1). The school counselor to the client: I think it is being preferred for you to choose the major of engineering because you have distinguished abilities in mathematics. (2). The school counselor during his interview with a talkative student uses the method of changing the subject (staying away from the topic) to put an end to the student's loquacity and his/her domination of the atmosphere of the interview. (3). The school counselor tells the client: You want to apply this solution about which the teacher told you; Why did you come here? You do not trust me! 1 (4). The school counselor: You cannot rely on anything else or any other resources except for me in order to obtain information about your problem. (5). The school counselor tells the student: Why would you make your parents interfere with the details of your problem? Their suggestions or solutions to your problem may be illogical or irrational? (6). The school counselor tells the student in the initial (intake) interview (their first meeting): I see that your problem is complicated and I cannot help in dealing with it. It is preferable that you look for another person who is more specialized than me and who may be useful to deal with your problem.
