Forbidden door

Why is the door forbidden?
The gate to the real world where I ought to be?
Why can't I remove my mask and reveal the real me?
Why must I keep myself safe and hidden?

If I could just tell all the things
Remove my wit and take the risk
My heart not bold, my tone not brisk
Believing beauty never stings

Alas, I'm spoiled and hardened now
Meant to wander on my own
Pretending that I'm made of stone
Greyness, still a silly vow

I do avoid a certain word
To scared to know it's real
I can't discover what I feel
Afraid of becoming a caged bird

So why is the entrance forbidden?
The gate to the castle where you ought to be?
Why can't you remove your mask and tell the things you see?
Shall I then keep my fears safe and hidden?
