the new hearing aids

Derek is one of these men who is lucky enough or unlucky enough in his opinion to reach 100 years of age. He can still walk and can read a book in a day. Of late his hearing has deteriorated and this became the regular topic of conversation. Firstly because the nurses do not do home visits to syringe any more so he had to go to the surgery to have it done. Then his hearing was not much better so he invested a lot of money in custom hearing aids. On the first day after they had arrived I found him fiddling around trying to get them in his ear.
'They will have to go back they do not fit' he remonstrated
'Shall I try?' I offered
This is not as straight forward as might seem. There is obviously a left and right hearing aid and unlike the national health ones they are not so easy to differentiate. Also, because they fit snuggly in each ear they are quite tricky to fit. I eventually worked out there is blue and red writing to indicate left and right and life was ok.

Two days later.
'These hearing aids aren't working again'
'Have the batteries run out'
'What in two days, I can't afford to change them that often'
It was the batteries but you are supposed to slightly remove them at night to save the charge. Another problem solved, and everything seemed alright apart from the fact that he would regularly take them out during the day and then complain they were not working when he had not quite put them back in properly' Almost every time I went in I was greeted with
'These hearing aids don't work they will have to go back.'
Two weeks go by and the hearing aid saga is beginning to settle down until, I walk and find him really despondent.
'What's the problem?'
'These hearing aids, I have spent a lot of money on them and now I think they are too loud, I think I will have to go back and get them reset'
'Am I too loud?'
'No you are alright but it's when I watch television'
'Shall we try them out now'
'OK but it's no good'

I turned the TV on and the volume was through the roof; it was so loud I could not get to the remote control quick enough to turn it down from 35 to 10 on the volume control. He had obviously had it that loud before the hearing aids arrived and not adjusted it back.
When I turned it down he said

 'Oh I didn't know you could adjust them from there.'
