My Favorite Tumor

You're like a tumor that is constantly on my brain
You really aren't the one to blame
Hopeless against your charm and humor,
So irrevocably smitten that you're my favorite tumor
There are times when I want you gone
Surgically remove you, and say so long
But I fail with every attempt I make
Even though it'd be for my own sake
Within time I always let you back in
Just so you can attach yourself to my brain once again
It's a never ending cycle that is vicious and fierce
I know that I'll eventually hand you my heart which you'll only sharply pierce
With the agony of the fact that you love me not
Instead you could care less if I were to rot
So, once again I'll surgically remove you
And hope that I'll be more cautious next time with what you're up to
When you try to settle back in as my favorite tumor
