the trait that can be covered up

A possible trait that can be covered up is dishonesty. People who are dishonest may try to hide or disguise their true intentions or actions in order to deceive others. They may manipulate the truth, present a false persona, or conceal their unethical behavior to avoid detection or negative consequences. However, it is important to note that covering up dishonesty is not a sustainable approach, as the truth has a tendency to come out eventually.
