Mechanical Paranoia - another song about you. Lyrics

What's the difference between
What I think about you and
What you think about me?
I hope there is none

Please call me

Last time I saw you
I was too tongue tied to say goodbye properly
I should have kissed your cheek
After our final embrace
And told you to phone me often
Cause I'm too scared to dial it
But if someone like you I love is ringing
I'll pick up

Please call me

And I hope I didn't cause too many problems for you
When you get back to LA
He's a dick from what you've told me
Who doesn't deserve you
I hope he doesn't get too angry at you

Oh please call me

And I hope you stay safe
Don't take the drugs that you hate
I know you find yourself in those situations
Just try your best to stay true
You don't need those things to have fun
You know that
Cause you had it with me
Or at least I hope so

Oh please call me

Who else back home knows about us?
I'm just curious
I have too many questions that
Seem like I might be trying to control you
But really I'd just like to know
I'm not gonna do anything with the information

Oh please call me

You don't have to tell me
But just don't forget me
You're the only friend I've got
The only person I love with all my heart

Please call me
If you can
Or when you feel like you need to hold my hand

Oh why do I dwell on things I can't control?
I'm just making myself sad
Why did I write another song about you?
I don't know
But at least it helps me remember
Those three good weeks

So please call me soon
I'd like to relive those memories

What's the difference between
You and me?
