ShoeInk I mean, if someone is spreading rumors about you in school or the office to damage your reputation, it can be pretty bad. You can't just ignore it. Imagine being called up to the principal's office just because someone spread a rumor that you've been selling your body to older men for allowances, or being passed over for promotion because your boss hears your colleague calling you incompetent and you don't refute it. Or rivals telling your lover that you are a playboy who cheats often, or lying to your best friend that you're a traitor. Yeah, you could claim that if your lover or best friend knows you well enough, they wouldn't trust rumors, but come on, that's impractical. Sometimes people need assurance, not silence, because it might seem like you're admitting it.
Just because you stand up and tell the truth, refuting the malicious rumors that people spread about you, doesn't mean you are as bad as them.
