Lyrics boundary issues - girlhouse

I kinda wish that I was manic
Though I took you by surprise
I think I put you in a panic
I could see it in your eyes
I guess I thought that we were best friends
Guess you're not looking for a best friend

You've become fully aware
So you act like you give a damn
And like I wish I came prepared
Could you please tell me who I am
Niceties aren't necessary
And now I'm getting kinda scary

Please don't wear me down
Just 'cause I'm smiling it don't mean I want you around

Please don't wear me down
Just 'cause I'm smiling it don't mean I want you around
