Just as a 'P.S.' to the above, it also occurs to me that Steve is making a mistake here. If he is so keen for us not to discuss Colin as a factor in Sheila's mental illness, then why does Steve keep bringing up?
It's really weird that he wants to deter discussion of certain topics that he deems 'sensitive', but then he keeps bringing these same topics up because in his weird, twisted mind he sees it as a stick to beat people with.
It's a contradiction. In point of fact, I only asked the question once, so why do you keep bringing it up Steve?
