“ if it is not right do not do it; if it is not true, do not say it.” - Marcus Aurelius

What Marcus is trying to say is to not false say something. So if  you're doing something wrong do not do it. And if something isn't true then don't say it. Pretty much is saying not to lie or do things that wrong to do. So if your friends are telling you to break a window and  you know that's bad then don't do it. First you don’t suppose to do it because it’s wrong and you don’t suppose to be doing that in the first place.  Also if people are saying rumors about people and you know it’s not true then don't believe them and start saying it to. You just have to stay quiet and not say anything because then you never know if they were lying and you're saying something isn’t true so you're pretty much going to be lying so don't do it. I agree to Marcus because if you know that you're not doing the right thing then don't do it because you'll get in so much trouble. And if you hear something that someone is saying about you or someone that you know don't listen to it because their is a 100% chance that their lying to you.
