it's you

If there's a reason why I'm smiling again,
It's you.
If there's a reason my heart skips a beat,
It's you.
And if there's a reason I'm humming a tune,
It's you.
I don't know what this is and I don't know who you are,
But I thank you for making me look forward to my every days.
You have no idea what you mean to me.
