3rd grader 

3rd grade. A place of pain....at least for me. 3rd graders are in that stage when they think they are really cool but really no one cares. You are considered cool if you have an I-pad and you are practically the queen/king if you hebe your very own phone!
And...mmm....if you can text! you are officially the representative of all things third grade.
It is also a time when the game of boys vs girls on a playground is reserved for the "popular" kids, it also means that if you are tagged BOOM you got urself a bf/gf. 3rd graders tend to think they are the coolest when really they are short and bothersome. They are very naggy but they think they are HILARIOUS. They are VERY annoying.

Mom:ohhhhh....good luck

3rd grader: annoying af

A 3rd grader at summer holiday

This is the type of kid whos becoming more and more of s normal person but is cringey idiot of a human being. Though there are rare outliers most are bad. Still though some of these people are actually good people. And if you wanna judge just by age than ur a loser you get me. Theyre mostly bad but npt all are. They also have a love for inappropriate shit they will change and become a 4th grader by the time theyre summer holiday finishes.

Person A hello im a 3rd grader but im at summer vacation! So when i finish summer i will become in 4th grade.

Person B oh your just some cringey screaming idiot who likes to be inappropriate
Person C dude not all of them are like that some of them are even pretty good
Person D shes a 9 but she will turn 10 next weekend 😏
