"We're always contradicting ourselves.
We want people to tell us apart....
...yet we don't want them to be able to.
We want people to get to know us...
...but we also want them to keep their distance.
We've always longed for someone to accept us...
But we never believed there'd be anyone who would accept our twisted ways.
That's why we'll stay locked up tight...
...in our own little private world...
...and throw away the key, so that no one can ever hurt us."
