Everything

How does it feel to be everything to someone? 

That I don't know. That's why I'm asking. 

I've been reading books, memes, and tweets about this "everything". It sounds cheesy, but it can swoon us over. And now I'm wondering how does it feel to have your "everything" and be "everything" to someone. Will I be able to feel it? Will I be able to have it?  

Hmmm. I'm just curious. Not that I want to have it right now, but when the right everything comes.
