That's Just How I Am This Is Me

Yes, that's just how I am. What else can I say?
You can never, ever figure me right out.
Sometimes a riddle, then the answer.
What's my secret? There's no secret at all.
Sometimes I am stubborn, I won't bend or sway.
Sometimes I give in both by night and by day.
Sometimes I argue and shout, then speak no more.
I only do what I want,
nothing more. At times I am strict, then too easy to read.
But I always remain true to who
I am. Yes, that's just how I am, and that's the whole truth.
Everyone in this life has a road to pursue.
I'll never change who I am or hide from view.
I'm madly in love with each color and hue.
Na-na-na-na-na.
Na-na-na-na-na-na-na-na-na. Na-na-na-na-na-na-na-na-na.
Na-na-na. Sometimes I am happy and laugh from my heart.
Sometimes I feel sadness when the evening turns dark.
Sometimes my heart opens, sometimes shuts the door.
