Iris Robinson, the affair and what goes on behind closed doors

It seems to me that people get most worked up about the things that touch them in some way.

Perhaps they see a trait in someone else that reminds them of something they hate in the themselves and this leads to intemperate criticism.  Or they are dealing with something in their personal life and it brings into sharp focus events in the social arena.  I could go on with scenarios but I'm sure you get the idea.

With Iris Robinson you have a series of curious events:

• She has an affair (brief by all accounts so far) with a very much younger man.  As a very broad generalisation one might guess that this means he was more energetic than subtle as a lover (very masculine one might assume).
• She denounces homosexuality in fairly fundamentalist terms in a public broadcast.
• She is married to someone with close ties to the Orange Order, a fraternal (i.e. male only) dressing up cult.

I suppose it is possible that she might never have been that stable and she has just completely lost it - a very sad state of affairs.  Or it might be that something came to her attention that very much upset her.  Could there be things in Peter's closet that need airing?
