If you're not an only child, then you've been blessed with a sibling or more who probably fall into at least one of the following categories.

The Flawless Overachiever 

This sibling is perfect in every way – straight A grades, trophies from sports tournaments, and has never received detention. They're basically everything that you're not, and your parents never fail to remember this fact during every dinner, or worse - family gatherings. You're forced to endure them gush over how your brother got an A++++ on his paper. Don't worry, your parents love you both equally. Yes, keep telling yourself that. 

The "I Got Your Back" Sibling

You've probably snuck out with friends for the first time and after you enter the house stealthily, you find that your parents are awake. Just when you think all hell is about to break loose, your older sister appears out of nowhere and casually responds with a "We just came back from the mall" and smiles innocently at your suspicious parents. You are safe. 

The 3rd Parent

Sadly not everyone is blessed with a cool older sibling. You may have thought your parents' constant yells of "Go study" or "Stop using your phone" or "Who's that boy you're talking to?" are too much to handle, but wait till your sibling decides to go into 3rd parent mode. From forcing you to show your terrible report card to your parents, to interrogating your significant other, the 3rd parent either wants to make your life miserable or is just practicing parenting skills for the future. 

The Leech

Whether it's that top you've finally bought after saving pocket money for months, or the last piece of cake that rightfully belongs to you, you can count on your sister to make it disappear. Try complaining to your mom and brace yourself for a good old family lecture on "sharing is caring", while your sister smirks at you from across the room. How she manages to look better than you in your clothes even after eating all your food is baffling. 

The Snivelling Snitch

If you thought the 3rd parent was bad, allow me to introduce you to the little snitch. If you happen to be a middle child with both an older sibling, and a younger tattle-tale, God bless your poor soul. This, usually younger, sibling probably possesses the Invisibility Cloak because no matter how careful you are or how hard you try to cover your tracks, the snitch always sees what you've done. They will then proceed to blackmail you, asking for cash or candy. The moment you hand it over, the snitch skips over to your parents, spilling all the beans while munching on the Kit Kat you just gave them. You have my permission to convincingly tell the snitch that he was rescued and adopted from a trash can. Bonus points for making him cry.

As much as I love my brother, I also hate him for being an overachiever, but I can't help but feel guilty about all the times I had snitched on him as a kid, so I guess we're even. I mean, what are siblings for?
