Butterflies In The Stomach

Have u ever realized?
That every time u materialize,
In front of my eyes,
My heart capsize,
My knees go weak,
And my brain starts to tweak,
Thinking up smart things to say,
Things that can make your day,
Things that can make you smile,
Things that can make u think about me every once in awhile,
Hell! I know I sound desperate,
And that I'm no expert,
But bear with me,
Cause I'm smitten by you and I can hardly control it.
