I've just read back over all the posts, letters and comments in the 'big question' stream. I think I've reached a decision of sorts. Here's how...

I fiddled with the goals, accepting what people said that 'happiness' is probably vague and unrealistic idealism when it comes to mum and dad, and as long as they are content we are doing fine. So for goal No 1 read 'content' for 'happy'.

I agree with my brother and, what is more, think that we are asking too much of ourselves to be 'happy' with any decision we make. So goal No 2 gets downgraded to 'content' too.

Next, we get to goal No 3. The question of keeping mum alert has passed us by with hardly a whisper. We have already sacrificed her 'alertness' for widespread peace and goodwill (a totally worthy cause, of course). I see that as one small pragmatic step towards an 'engineered' solution, and that many others are going to follow just as easily. I'm almost ready to ditch goal No 3 completely in the light of this. Why not just do it?

So the goals look like this now:
  1. to keep mum and dad content
  2. to keep the rest of us content
  3. to keep mum and dad alive
I agree with Gail Rae Hudson that any form of uncontrollable incontinence is a reason for moving to care. Consider that now part of the list of no-brainers. For mum, 'violence persists' has to now be made 'violence returns'. She is living on a suspended sentence - and doesn't know it.

Two other cons on the nursing home side:
  • Loss of control over medication - a serious problem for many others, and a potentially aggravating one for us too. We have already had a taste of some of the frustration of loss of control in our complex dealings with the social services. I do not look forward to more of this.
  • My nephew Connor correctly points out that once mum and dad go into a home our predisposition to leave each other unacknowledged for several decades at a stretch may reassert itself - and they will get few visitors. While I am not willing to talk on behalf of Rachel and Greg, who I assume will behave much more commendably than me in this respect, I think this too is a serious drawback. I know I just won't visit. I will go on occasions, to pay my dues, to perhaps offer a bit of familial pleasure, but if I am not recognised, no longer missed, or pleaded with to effect a great escape, I will keep visits to the minimum. I will no doubt feel remorseful when it is all over, but that is my personal predicament that no-one else can share.
So here is my decision: I will wait for the accident that will force our hand. Until then I think we may as well shore up the precarious life mum and dad are clinging to at home.

Somewhere out there there is a Mack truck bearing down on us (I imagine a shiny metallic maroon-coloured one, travelling by night), and we'll meet it at some intersection point somewhere in the future. The car-crash may be a slow motion version, or it may be all over in a gasp and a sigh, but I feel better waiting for that than taking the earlier nursing home alternative. I remember a saying that was popular in a company I once worked for - if you're going to amputate the arm, don't take it off knuckle by knuckle. I may be making this far more melodramatic than is advisable, but I feel that if life has to go, it is better if it goes all at once.
