heard it all before

i'm so tired of staring at the wall, but i know i got to put you down, and i keep trying to make sense of it all, but i can't keep going around and round, and you know me well, you know me better than this, and i can't be sure if you're something i'd miss, cause i heard it all before, i've heard it all before, i keep finding a little piece of me, everytime we disagree, and your words float like dandelions every other way, i can't keep listening to what you say, cause i heard it all before, i've heard it all before, and i take everything i can and i'll throw it out the door, ya, i've heard it all before, i've heard it all before, and i take everything i can but i've heard it all before
