Be careful when you walk along
The edge of the water
Be careful you don't slip
And lose yourself
'cause I don't think you can swim
I know that you can't swim
You're drowning from within

Be careful you're not
Listening too much
Be careful not to try
And see what you can't touch
'cause I don't think you can dream
Of things as they shoud be
You're dying from within
