Not the Girl

What do I have to do
For you
To want to
Give me your phone number?
Ask me for my phone number?
I can't even remember
When someone asked for my number
But I guess it doesn't matter
When the phone never rings
When the fat lady never sings
Securing many of endings
But after all
I'm not the girl you want to call
I'm not the girl you want to have call
And have to talk to
When you have more important things to do
Don't you?
I don't really matter to you
