'If your so call friends urge you to do anything you know to be wrong, YOU be the one to make a STAND FOR RIGHT, even if you STAND ALONE. Have the moral courage to be a LIGHT to others you follow' 

What this quote means is that real friends don't force you to do bad things like smoke, drink, and etc fake friends are people that will force you to do bad thing your not suppose to do they also turn you back on you.
