As long as you understand that naming something takes away power from it, I have no problem telling you words for the things i have experienced. I would like you to realize, however, that What I mean by 'naming takes away power' is that when something is simplified into a word, it becomes easier to define, yet jjust as easy to dismiss. With that in mind:
trust, honesty, communication, understanding, compassion, humor, passion (not lust, there's a difference), as well as an eagerness to grow and change with and for the person you care about.
(note: I know I've missed a few, but it's late and I'm tired.
