My heart is pounding pounding

I feel like I'm in love for the first time.
I don't know how to react to what your saying.
I can't stop my heart from pounding outside my chest.
I'm too nervous to say anything so I nod.
I sit as I try to think of something to say.
It's useless, I am trying to hard when your so good at it.
I can feel my face is all red and hot.
I can't think of anything, still.
