Lyrics:

Would you ever thought of this, a split at the seams
And I was careful enough to keep my questions to
The least level of what I thought you could handle

And I was 17 and you kept on changing the plans

Breaking into houses for the sheer thrill of the crime
Was funny at first but I turned 13 and it got
Harder to not get caught with the goods 

And I was 17 and you kept on changing
Plans were more complex cause the cop cars 
finally stepped up to bat.

Enjoy!
