Living in a big city, I attended funerals if I had known the person who had died, or knew a relative well.
However, in the years where I sang in a church choir, I learned to appreciate those who turn up out of a sense of duty, as there was nothing sadder than a funeral of someone who had died alone and unloved, and where apart from the parson, organist, sexton and two singers went unattended to his grave.
Living as I now do in a small country town, I realise that here it is still the done thing to attend if you have had the slightest acquaintanceship with the deceased or the family.
If the funerals your husband attends give a reasonable chance of meeting friends and relations he otherwise is out of touch with, I understand why he goes.
I also can appreciate his going if he is making up his mind about what he wants and intends to leave complete instructions for whoever has to deal with it when the time comes.
One thing we can all be certain of is that we will all die sooner or later.
