RIGHT
"Always do right" 
           -Mark Twain 

I think this quote is trying to say is better if you choose the right. Because to choose the right then choosing the wrong. Also right to be alone than being with someone because it makes you to be focus on you. For example, if your friends invite you to a party and you want to go but you have finals tomorrow. So you stay study than going to that party. That's why always choose the right and have a better future. When you choose the right you know you're doing something good and feeling good about yourself.  Choosing the right is  like respecting others, doing what's best for you, always be loyal, etc . Also choosing good friends that always be there for you. Also always doing right, you good graduate from school and having a good career.  

              Right 
"If your so-called friends urge you to do 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."  

I think he's right because true friends will always be there for you no matter what and some friends will not be there for when you need them. For example, when you're sad or somethings true friends will always be there yo courage you and some others won't be there for you. Another example is that true friends will never leave your back and will always be right by your side and others won't there just going to leave you alone.
