Unexpected Surprise

You're an unexpected surprise,
a little escape from this boring world.

I've got to keep this secret,
I've got to keep my lips closed.

My heart's in your pocket,
just make sure no one else can see.

There's a smile on my face when no one is looking,
a glow that could blind them.

I thank you for giving me this,
I thank you for giving in.

If I'm not careful,
you could become my everything.

Neither of us want that,
or is it just you??
