Social or peer pressures are quite common among school kids and adult. They can't be blamed because it is by their age that they begin to find comfort, solace, and fun when they are away from home. While some peer pressures may positively influence their peers, others can adversely degrade self confidence, personality, habits and schooling.
Having been in school for over a decade, I have seen students who wreck their education because of bad choice of friends. Normally, they resort to gang fights leading them to injury and end up on exam table for serious medical attention.
It is then important that parents / guardians and school personnel closely guard students, their behavior and performance, so, interventions can be promptly given. If students are well guided and personally motivated, they can go through social pressures with less difficulty.
