Terrible thought

A terrible thought has moved into my mind
Like an unwanted room-mate drunk on wine
It feeds on my unhapiness, won't pay the rent
I must take proper measures to evict it
A terrible thought has moved into my mind
A giant rat that's nibbling on my pride
It's tearing away my patience and my wits
I must take proper measures to set a trap for it
What a terrible thought
I don't care what you've done
I don't care who you've won
I know in the end, you have your fun, but you can't have ithere,
And I won't let you steer,
You know I don't want you in my mind
What a terrible thought
What a terrible, terrible thought
I must stay calm you know and I must be clear
It's gonna take a hundred thoughts to make this one disappear
A train like that can travel a soul for years
A terrible thought can have a terribly long career
What minds have you shredded
I bet they regretted
Having ever thought you up
Just look at you shine
Commiting your crimes
You know I don't want you in my mind
'Cause you're breaking my stride
You poisonous vine
You're strangling me inside
You're breaking my stride
You poisonous vine
You're strangling me inside
You're breaking my stride
What a terrible thought...
Father :
What is your greatest worry because
you seem to be worried all the time
Daughter:
Sometimes I can't hear myself think
Father:
You have to speak a little louder,
I can't understand a word you're saying
Daughter :
Sometimes I can't hear myself think
