Yes, I agree with Mastodon. My teaching experience is why I answered this as a T's probably hope to have hope which is very much what teachers and probably most helping professionals experience. It is naive to think I will save every student. That doesn't mean I don't try. That doesn't mean I don't look every single day for that opening, that possibility, that hope. But there are cases, fortunately rather rare, that there is absolutely every barrier, roadblock, obstacle getting in the way of making any inroads. Hope is hard to see, hard to find in those cases. It isn't that I stop trying to find that hope, but hope can be terribly elusive in some cases. I suspect T's experience much the same.
