a black mark: o que isso significa?

As adults we should take responsibility for everything we do. Sometimes we do things that are wrong, and those black marks might be against you for a very long time. But wait, a black mark? When you have a black mark against you, people still remember things you did in the past that was wrong. For example, you get out of a very difficult relationship and your girlfriend broke up with you because you cheated on her. That will be a black mark for a long time against you because other girls that might be interested in you when come to know about you cheating on your ex-girlfriend might not want to date you anymore. So that will be your black mark. That's it for today. Take care!
