Just to point out that Twinkies first substantial post here (2.57 yesterday) is VERY supportive of DL's position, and asked pertinent q's about his dw's responsibility in this. It didn't get heated until, DL, you started 'qualifying' the way violence erupts and offering 'buts' alongside your central admission - which is good, honest and admirable - that it is not OK. Ooops, actually feel that I am doing what I think you are guilty of...pursuing the less important tail feathers of an argument once the important bit has escaped, IYSWIM.
Don't have any experience of OCD, but I do know that I am determined, bloody minded and have a fairly heavy touch on any controls I get my hands on. While any of DPs habits bug me, we are in difficulty, and I spend hours in totally unecessary misery and tension. I have learned to consciously almost role play someone who REALLY doesn't mind that he prises open jars with the tips of the (my!) Sabatier knives, and I immediately feel much happier myself. And the relationship is better for it.
