A girl who thinks she is old enough to do whatever she wants, sometimes going through the "scene" phases. She tries to fit in with older people usually. Most of the time this person looks older than 13 or tries to act older than 13, she usually dates people older than her. She tries to be adventurous and tries new and dangerous things.

Friend: "she's a13 year old girl.."
David: "omg, she looks so much older than that"
A “14 year old girl” will seek attention by any means possible, like fake depression and nudes. Not all 14 year old girls are like this but most of them are. Be smart, don’t act like a 14 year old girl.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
