Analysis of Hidden smile

I have a smile, bright and true.
Yet I choose to keep it from you.
Like a secret, it rests on my face,
A silent happiness I won't embrace

I have a smile, hidden deep within,
A world of joy, I dare not begin,
For the world around, so unkind
It's not deserving of the peace I find

I have a smile unseen by your eyes,
A treasure I hold, a sweet surprise.
But in your presence, it wants to shine
To share the warmth that could be mine

I have a smile longing to be revealed
To let you know how my heart feels
But alas, your actions so unkind
Tell me that you are not worth my time

So I hold my smile, tightly confined
Knowing it's best, the smile of mine
For you may never know it's genuine glow
If you do not appreciate the love I bestow

I have a smile, hidden away,
For those who cherish, respect, and stay
But for you, who doesn't deserve its grace,
I'll keep my smile and it's sacred place
