I'm the oldest of 5 and can relate to aspects of being the eldest and an only child, especially being dully (and duly) conscientious and perfectionistic. My sister is competitive and rebellious and my brother is irresponsible, fun-loving, and irreverent. My other two siblings are almost a generation younger, so they have their own dynamic, though probably more like only children, even if my sister, brother, and I helped raise them, too. Birth order has definitely influenced aspects of my personality, though I really didn't like being saddled with the extra responsibility of being an example or living up to high expectations set by my family. Adulthood cured much of that, thankfully. I do appreciate that I'm very close to my siblings and parents because of it, so it wasn't a complete hassle.
