Having a sibling can be one of the greatest assets and experiences in your entire life. You have an already locked in friend who will love you and look out for you and shoot NERF balls around the house with you.
That's not to say that having a brother or sister is all butterflies and rainbows and ponies. Having a sibling can also set you up for some crazy competitive streaks and ruthless pranks. Hell hath no fury like a younger sibling trying to one up their older sister for always taking all of their money in Monopoly. And that sh*t just gets worse as you grow up — except now it's borrowing their clothes without asking them first. My advice? Don't get caught.
It's pretty cool to share the same genes with another person, so the next time you can't stand your brother because he's being an annoying little twat — just remember — it could always be worse. You could be an awkward and weird only child! Just kidding… kind of.
