It's about the END.

What done is done. Everything has a STARTING and also an ENDING. Who cares about how you feel after all? Who else will even care about how hurt you've been through all this time. Human are selfish, like I said.. No-one will really care about you instead of themselves. Lastly, WHAT DONE IS DONE. NEVER REGRET, NEVER LOOK BACK, NEVER TURN BACK, NEVER FEEL SAD.
