People who demand nothing of you
At first, I had "ask nothing of you" but it didn't quite feel right. It felt too detached, like they wanted nothing from others, like they never invited you to things or asked for commitment, and this isn't true of the people I'm thinking of. The most charismatic people I know, who seem to have this radiant, magnetic quality to their presence, are actually those who actively invite you to things with your best interests in mind but are totally okay with you declining, and they really mean it.
