"He that walketh with wise men shall be wise: but a companion of fools shall be destroyed" 

This quote is trying to tell us that we choose who we want to be. Either we want to be with the people who are the ones who are good play sports. Or the ones who always choose the wrong by staying up passed their curfew. For example, if you hang out with your so called friends and you fail each class or do something bad then they will not back you up because they do not want to get in trouble. And if you don't like that then hangout with the good people. The good people who study with others who play sports and who absolutely don't judge others or bully no one.
