An older sister is a female sibling who is born before another sibling. She often takes on a nurturing role, providing guidance and support to her younger siblings. The relationship can vary widely, from close companionship to occasional rivalry, depending on individual personalities and family dynamics. In many cultures, older sisters are seen as role models and caretakers. They may help with homework, share life experiences, and offer advice. The bond between siblings, including an older sister, can significantly influence emotional development and social skills throughout life.
