Hollywood stereotypes teachers as the huffy-puffy type that everybody hates or the cool one that's everybody's friend. According to TV, the former is bad for education, bad for kids, and should be removed from the planet with a spear, a pitchfork, or some other painfully sharp object. The latter, according to TV, should be commended because they care about kids.
As with many issues, Hollywood has given a false portrayal. Although teachers should be friendly with students, they should never be friends. Although teachers should be supportive of students and even involved in their educational development, they should never be friends. A teacher student
friendship is not healthy.
