Something was repeated or played repeatedly-the memories, the happiness, the pain. Just like the familiar scents that evokes a core memory of the one that got away.
If you'll be given another chance...would you mind repeating it?
"I've tried to ignore it, but I can't anymore,"
"Holly, we shouldn't ,"
Knowing something was so different than believing it was wrong. You could know it was wrong and not believe it. Forcing yourself to think it wasn't wrong because you believe nothing bad could happen.
