If it makes people more relaxed about the subject, all well and good. It has been constantly on my mind since my wife passed away thirteen and a half months ago, to-day. I've got her ashes at home.
But, don't make them (the coffins) look to tacky.
Now if I (we) was in New Zealand, I think I would join for the company and socialising side of things, a country we enjoyed very much on two occaisions, because I do not see much of that here except for the neighbours, mainly in the summer months. During the winter ones things are pretty much 'dead'.
