The Extrovert who tried to be an Introvert ..!

In my high school, there was this girl; actually she was my friend.  An extrovert. A social butterfly. Loud, noisy and also fun.

If we asked her she'd sing a song, perform an act anything.

Normally extroverts are popular, but this girl later started to get the disliking from others.

There was a metaphor among the girls. “you sound like Tesa”/ “don’t talk like Tesa” etc.

By that time, there was a rumour among every one that introverts are bright students, they get top marks.... 
(this rumour still exists despite of its validity.)
