Yours Faithfully, An Aspiring Introvert

Finally, I hold the key
To my heart
Whose contents are set
According to my variable moods
They differ every day, every moment
And I choose to unlock it
And tell you all what it holds
For it tells not only my tales
But some of yours too
And I am spilling the contents
Hoping you see yourself in me
And excuse the mess
So, let the tales begin.
