"If your so called 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 for others to follow."

-Thomas S. Monson

I agree with Mr.Monson that you should not have to do what your friends want to do if you know it is not the right thing to do. You do not have to follow everything someone says only because they are your friend, you are your own person that is responsible for your actions. You should be a person others would look up to, it is better to be a good influence than a bad one. Even if the others may not agree with you not wanting  to do the bad thing, you have to stand up for yourself  no matter what. If they will not listen to your reasoning then it is their loss. If your friends want you to try alcohol you stop them and warn them of the consequences to their actions. Your best option is to not participate but interfere if they are about to something else that is not good. You have to have control over your own actions and know when to stop and when something bad will happen, even if you are the only one who knows it. True friends do not frag you into doing something bad just because every one is going to do it. Good friends to not put each other in danger or force them to do something they do not want to do. Be good good person and choose the right no matter what the circumstances are.
