So hard to choose, I love the lyrics from Schizophrenic Conversations that others have already posted. Some other favs are:
"Well I know the words, but I can't really speak them...to you" and "the walls you build around yourself, I guess they also keep you here"
Sorry, but ive thought of another few lines, that mean a lot to me:
"I can't explain how I feel, I've been there many times before, I've tasted the cold steel of my life crashing down before me"
I love what you guys have all put, i find each day, my view changes, there is always a line in one of stainds song, that reflects how i feel at any given moment.....and thats why i gess my facebook statuses are often staind lyrics.....most people look and wonder wtf!!! lol
