Ugly duckling syndrome? Urgent question!!?

So, there's this girl, and ive known her since 7th grade, and we havent really talked that much. but in 7th grade she was so pretty and i really liked her. she used to be really smart, cute, talkative and chatty but i dont know what happened.then in 8th grade and she was in one of my classes and she sat right next to me... then somehow she became very quiet and barely uttered a word, and she started tying a low nerdy ponytail everyday and she seemed like such a nerd. she was a pretty innocent/sweet girl tho and did not cuss or be perverted like the others...idk y but she bugged me and i always got annoyed with her because she was so quiet..and she wasnt as smart as before...i dont know what happened..? , she was such a nerd and i sometimes hated her and she was soo quiet! and she became soo uncool! and then she wore this perfume or something which i didnt really like the smell of and it made me hate her even more... and when i passed by her i felt resentment towards her...?she also dressed plainly and a couple of times she smelled funny( please dont judge me and call me mean- idk she really bugged me a lot)

but now, were in high school, and she's blossomed into this really pretty girl now, and i like her again.. it turns out that she is a model too- not a famous one, but in fashion shows around the area, and it turns out that her parents were models when we were in 8th grade- and she also did one fashion show then!

now, i cant believe my eyes.. she's let her hair down now out of that pony tail, and i really like her but i really dont know how she changed so much! she's now popular and chatty again and stuff! oh and i know she wouldnt have gotten plastic surgery, everybody says she hasnt even her best friends and she just would not be the type to do that!

i mean, have i been seeing clearly? how did she change so much! and i want to tell her i like her and

be her boyfriend :)

btw, my name is sara on the username because im embarassed anyone will find out who i am!

how did she become so pretty!!
