I was unclear. Sorry.
I don’t consider the occasional question I ask a priest to be formal spiritual direction. It’s how I continue my spiritual journey until I find my next SD. The level of trust you speak of does require regular time spent getting to know me and my particular challenges. At the moment, I don’t have recourse to that but I think it’s better to have my questions answered in a general sense than to leave them completely unaddressed.
I do agree that an SD should not be a personal friend. In fact, I have met many SDs who will not direct their friends (or members of their families, or anyone employed by their respective parishes). An SD should feel free to say what (s)he thinks, even if doing so is hard for the directee to hear. Frank discussion of delicate matters could put an existing friendship at risk; in this situation, an SD might be reluctant to be frank, and that could result in less beneficial direction.
