She constantly changes the way she looks and acts
A girl I know constantly changes her appearance and personality.
The way she looks constantly changes like dying her hair all the time, changing hair styles, wearing different styles of clothes all the time etc. Every time I see her something about her has changed.
Her personality is worse though.
With every person she meets it's like she completely switches who she is. With some people she is wild hyper then she's calm and layed back with another and with some people it's like she tries out different ways of acting to fit them and it's freaky because of how good she is at it.
Today she completely snached a girl I knows friend group because of how easily she was able to communicate with them and the way she acted drew them in.
That's not all, when she's with me the was she acts jumps from calm to hyper to moody then happy and all over again.
She knows how to read people and uses it to her advance. It's like she collects people just for the fun of it.
People are always caught in her trap and it's impossible for everyone to realize it.
