It's been a trend among teens to hug each other as a way of greeting. However, this practice had gotten out of hand. These students just openly and unnecessarily hug each other anywhere inside the campus and this has called the attention of school authorities. Now the practice of hugging is no longer allowed. Hugging on campus is prohibited as a form of greeting most especially if it takes longer than 2 seconds.
Shaking of the hands or merely nodding of the head with a smile is enough greeting while on campus. Hugs are unnecessary and too distracting to the school environment.
