Her

A missed opportunity? It's what I do best.

Don't know why I'm surprised, I really should have guessed.

Of course, you're with her, why wouldn't you be?

You're a catch, it's not hard for anyone to see.

And she's pretty, so pretty, I bet she's funny too.

And the way you look at her, she mirrors back at you.

You look happy, I'm glad. No, really I am.

I mean it, you deserve it. My words are not a scam.

She'd be a fool not to love you completely,

And you should be loved indiscreetly.

You're a star in a sky of black

You're a crystalized gem and I'm cracked.

So, of course, you're with her,  why wouldn't you be?

You're wholeheartedly in love with her, anyone can see.
