Strange, yeah.
Believe me, boys and girls of her and my generation don't do that in a relationship. We can spend time with cell phones in hand but the physical contact is always there. Even Malia also understood. Leora is the first and only girl in the world that I have seen holding a pseudo relationship only, ONLY, through phone calls. While living in the same city and not too far away.
It's not even a sex-only relationship because she herself says she's not so important (and seeing that she's at home today, Saturday night ... I believe it).
In short, a unique and rare case that should be studied.
