The leg between your left and right.
Your middle leg is generally shorter than the left and right, however can grow to astonishing lengths in some.

A young person between the ages of 10-14, give or take.

Also the beginning stages of puberty, so expect your sweet little elementary schooler to begin changing in the most horrible of ways. Most middle schoolers will struggle with puberty, some more than others. Most give in to their hormones and act with carnal instinct, becoming obnoxious foul-mouthed babies with no respect for anyone-- this is due to the fact that they are confused and have absolutely no idea what to do with all of these new emotions and are trying to compensate this "weakness" by acting like brats.

Other middle schoolers at most will develop some lip, but are able to control their urges. When they go into high school they are generally more prepared to deal with high school, which is to be described almost as a breeding ground.

Middle schoolers are NOT to be confused with highschoolers. Middle schoolers are still in the "opening" stage of adulthood, whereas highschoolers are rushing through the "blooming" stage and "settling" stage. Middle schoolers are very experimental as they begin trying to find their identities, not knowing that identities are not found but developed.
Specimen A:

BEFORE Tony became a middle schooler, he was a very polite little boy who loved to share his toys.

AFTER Tony became a middle schooler, he grew out his hair and kept it greasy, dressed in black, talked back to teachers, talked about sex and harassed girls without actually knowing anything about sex, watches rated R movies and says things to purposely breaks his parents hearts. Lies about things he likes to impress other boys. And girls. Deep inside is still that polite little boy who loves to share his toys.

Specimen B:

BEFORE middle school, Maria likes to help people and read books.

AFTER middle school, Maria wears skanky clothes and hangs out with lots of boys and talks about boys, she also has a million best friends and newfound sisters and also lies about what she likes to please other boys and girls. Deep inside is that sweet girl that loves to help people and make people smile, and read a good book once in a while.

Ah yes, the worst years you'll ever have in your life. 6th graders are immature and look 5 years old, 7th graders like to talk shit and make dirty jokes whilst bullying the 6th graders, 8th graders want to go home but not before they post every breathing moment of their life on Snapchat and ask to get laid (but like no one wants to touch your zitty ass) Middle schoolers like to wear Nike and Adidas even though they both suck, they listen to rap music unnecessarily loudly, and they add the words "gay" and "faggot" into any sentence. You can find these idiots riding their bikes down the street making moaning noises because they think it's funny. Some advise is to wear deodorant because y'all smell like a petting zoo on laxatives. You also have to respect your upperclassman because you'll get a show up your ass if you don't.
7th grader: haha hi baby!

Random person: who are you?

7th grader: your mom! hahahaha

Random person: oh wait, there's a middle school near here, so this must be a fucking middle schooler.

It's Elementary extended and you hear a lot more cussing and swearing and no one gives a shit if you do like in 4th grade. The girls start wearing shirts that show their cleavage more, despite the fact teachers will try to get on you about that. A place that will make you want to commit suicide, due to all of the mental and physical abuse you go through while you're in middle school and the teachers will just "teach" you shit that you will never use. Parents will get on you more about homework when you would think that it would be enough when kids are fucking with you all day. All of your friends will change and get into drugs more and it may surprise you who it will be. You better prepare for all of the bullying you will go through, from kids ages 12-14 when you're at school and on the bus, it'll be 12-18!!! Middle school does not give anyone mercy, whatsoever, unless you're a fucking jock then no one will fuck with you and you'll be the one who will decide which person deserves mercy. Middle school is (one of) the worst place(s) on Earth and you will have to learn how to survive through middle school. Good luck.
6th grader: Yay!!!! I'm in middle school now!!!

8th grader: Yeah? Welcome to HELL!!!

6th grader: W-w-w-what?

8th grader: You heard me you little shitbag. Listen, this isn't like a walk in the park you dumbass. Middle school is the worst place ever and you're acting like it's going to be great! Well, guess what? It will be hell for all three years while you're here. So unless you are 100% prepared and you are 100% mentally and physically fit for this shit hole, I'd suggest you beg your parents to home school you. Well, it was nice talking to you! Oh, and have fun.

6th grader: Aw, shit...
