You there?

Hey!
I don't know what are you upto?
But, you are a glitter on the dress I wear.
I don't know what are you doing there?
But, I am waiting here to see you everyday.
I don't know what has happened to you?
But, you are the best I could ever get.
I don't know what am I to you?
But, you are the smile on my face.
I don't know what are we today?
But, it has to be a beautiful tomorrow.
