Sometimes some people just love to take a good slip of advantage(s) towards others, which is not a good thing to do. As an example, an ignorance student may take an advantage of a good teacher by not listening to his advice/ instructions. That teacher don’t have to be an innocent and decent teacher, just being nice is more than enough. For the first and second offenses, may be the teacher can be lenient, but if the student keep repeating the same thing the situation may go really, extremely wrong and dangerous especially to the student himself. A nice, belly two shoes teacher may turn to the student’s darkest, deepest nightmare. The lesson here is not to make a good person turns bad as it may become uglier than we might expect.
