What does "I love you" mean, when said by 2 people who love everyone?

I'll start with a small thought, and you put in yours, and everybody respond to everybody, LOL, like a creative mess.

So, I'll start with 2 things:
1) Deb, (the friend that introduced Grace and me), asked Grace last month: "Well, have you and Doug said 'it'? Have you said 'I love you'? Grace explained that for both of us, love is a basic part of our ways of Being, and that we'd said it pretty early on. So Deb said: "Oh, that's right... you both love *everybody*. So... how do you handle saying 'I love you'? What does it really mean?"

2) Grace and I have a relationship that's built not so much on "identity", as built on Being. It's enough for both of us that loving energy is powerfully present, and that we both consistently access it and bring it. It doesn't need to be so "personal"... we don't have to put each other on pedestals, or say "You're the only one I could love like this..." or "You're the only one I love". Being is first, shared intention after that, and little attachment. We're not "attached", we're "connected".

How about you?
How would it be, if you, and the person (or people ;) you're intimately involved with, loved everyone?
