Gracesgran, I'm afraid you are right about too many professionals.
I have heard so many times of doctors/social workers, etc. saying for example, 'Well, if she can't remember to take her tablets/how to use the microwave, etc., all you have to do is write it down for her/phone to remind her,' etc.
Even if they've 'been on a course', no conception of the practical realities - I.e. someone has to remember to look at what you've written, and remember after turning their eyes away, to do it!
Equally, to remember what you said on the phone for the time it takes to do whatever it is.
And what can be particularly frustrating about these clueless professionals, is that because they ARE professionals and you are not, they think they must know better than the one who sees the person in question all the time.
