I love sarcasm and dry humour but I think you have to be careful with it, as it can mock and wound if delivered with contempt.

An example of gentle sarcasm: the other day I was wrapped in a blanket at T, I stormed off across the room and sat in a chair, and he came over and adjusted it, kind of like tucking me in. Later, I said I assumed I imagined that as I had thought he was angry. "Ah yes," he said, "Because I always like to tuck someone in when I'm angry."
