"Always do right"- Mark Twain

This quote means that by do right, always do right. You don't want to become a wrong person there's not a lot of opportunities for them. You want to become a good person always choosing the right. Before this there was another one about bad company that we shouldn't be surrounding our self with. We should be surrounding by positive. "Always do right" to me sounds like its all there like there's no explanation needed. For example when you did something wrong and balm your sibling that's wrong you shouldn't do that take responsibility so you do the right thing and go up to whom ever owned it and say I did it. You might get some consequences but they'll know that you owned up to them and saying that you did it.
