Diamond exterior:
You want to have no remorse
You want to be cold as ice and as unforgiving as fire
You want to tear the world down and watch everyone run in fear
You want to hurt people the way they do you
You want to inflict pain upon them  tenfold

Marshmallow Interior:
But you know you cant and even if you could, you wouldnt.
You help the teacher with extra things she doesnt have time to get to
Your friend tells you she cant deal with you but you still  talk to her when she needs you
You fall in love with her and want so bad to hate her but you just cant
You care too much
You care for those who will never appreciate you
You care for all the wrong reasons
You care for all the wrong people
