Some of us seem sturdy, but we're built on shifting sands.
Some of us seem solid, but we're hollow in the middle.
Some of us seem happy, but we're faking the smile for you.
Try distinguish us - you'll never get it right, we're too adept at pretending. You won't hear our screams in the night, you won't see our wounds in the day, You won't know that you're seeing one of us until we tell you.
Sorry to be the one to tell you that you're comfortable in your blindness.
