Lyric discussion by Polemarch 

Cover art for Words lyrics by Darren Hayes

Agreed, this is such a beautiful song.

My interpretation is that this song is aimed at someone Darren's very close with, but she's very reserved, always being careful to say the right things. He's asking her to be more open and candid with him, even if it means that she says some things that are hurtful - words like weapons.

He's afraid of damaging their friendship ("this delicate thing we've made"), but at the same time he feels that the fear and existing relationship are holding them back from truly communicating ("weight above").
