I would say that occasionally my T will say something that ends up being triggering to me (but I think all T's do that accidentally on occasion). But the one major thing that she does that I only recently told her bugs me (I should have said something a long time ago) is that she says "poor thing!" in an attempt to be empathetic or show me that she understands what I am feeling. But I always hear it as a mild mocking or minimizing of how I am feeling, even though I logically know she doesn't mean it like that.
