When does it matter if people know about my mixed heritage or is it nobody's business?

This is about sovereignty—knowing when sharing serves *you* and when it doesn't. Sor Juana lived in a colonial caste system obsessed with blood categories, yet she claimed her intellectual life anyway. She chose what to make visible and what to keep private based on her own needs, not society's. You get that same choice. In some spaces—when you're building genuine relationships, when it affects how someone understands your experience, when you want to be fully known—sharing makes sense. In other spaces—job interviews, casual acquaintances, people who've shown they can't hold complexity—your heritage is your business alone. The key question isn't "should I tell them?" It's "what do I need from this relationship, and what do I trust this person with?" Sometimes silence is strategy. Sometimes it's self-protection. Sometimes it's both. Pay attention to your gut. If you're constantly calculating who deserves to know, that's also information—it might mean you're in spaces that aren't safe enough for the full you. That matters.
