Sara is angry with Grissom when he rejects her for the final time.

Grissom had rejected her for the last time. 'He asks me if I want to go to dinner with him, a week after he says no to going to dinner with me! God I hate him sometimes!' Sara walked down the hall, fishing her keys out of her pocket. After a short trip to the locker room, Sara heads out for her Denali. She slams the door and leans back. She clicks the radio on, and fiddles with the dial 'till she finds a station. "Finally."

# You change your mind
Like a girl changes clothes
Yeah you, PMS
Like a bitch
I would know

And you over think
Always speak
Cryptically
I should know
That you're no good for me

Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up

You,You don't really want to stay, no
You,should you don't really want to go-oh

You're hot then you're cold
You're yes then you're no
You're in and you're out
You're up and you're down

We used to be
Just like twins
So in sync
The same energy
Now's a dead battery
Used to laugh 'bout nothing
Now your plain boring
I should know that
you're not gonna change

Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up

You,You don't really want to stay, no
You,should you don't really want to go-oh

You're hot then you're cold
You're yes then you're no
You're in and you're out
You're up and you're down

Someone call the doctor
Got a case of a love bi-polar
Stuck on a roller coaster
Can't get off this ride

You change your mind
Like a girl changes clothes

Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up

Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up

You,You don't really want to stay, no
You,But you don't really want to go-oh

You're hot then you're cold
You're yes then you're no
You're in and you're out
You're up and you're down #

"Totally right." She laughed, as she put her Denali into gear and drove out of the car park.
