Can anybody help me form my character's personality?

Chewing way too much gum at once.

@zophu thats a great idea and i was actually thinking about it but some of the lines she has I stumble over even without wads of gum in my mouth :)

Farting and blaming it on others?

Smoking.

She is a secret drinker

How old is she? How old are you? What does she/you look like?

@ChocolateReigns she’s about 14 years old. I am 13. Shes a skinny, tall, blonde.

What kind of a play is it? I think twirling her hair would be an easy bad habit. Or maybe chewing it.

I knew an actress who always inserted ‘um’ into her lines. Not a good idea. How about rolling your eyes whenever anyone says something that undermines your image? Your director will say to stop if it doesn’t work. (I hope)
