Cover art for Sins of My Youth lyrics by Tom Petty & the Heartbreakers

Regret and heart felt loss so well said in this song. She must have been someone special.

When the past gets up in your face Memories slide out of place All those things that were hidden away Ain't so bad in the light of day

My take on this verse is that you have lost touch with what was good in the relationship. Then is the next verse a futile attempt at asking for forgiveness.

You say you love me, wish you liked me more I'm no angel, that's for sure Said you forgave me each time I was caught But you still paint me as something I'm not.

The Heartbreakers sound amazing.
