I wonder if I have ever known the feeling. Perhaps not. I have a vague idea and given my experience and plentiful reading done while people have actually been having relationships, I’d say I probably am not too far from it. I connect it with general care, but also with something emotional and something spiritual.
Connection, dedication, fondness. Respect is there, as the three mentioned before cannot really exist much without respect, but respect is more of a distinct matter (except it has to be there, as I have said).
