I've thought that it's a interesting thing to discuss as long as some have after death wishes...

I saw a movie with that made me think that I would choose a dark red coffin for my burial..

I don't know if my wish will come true or not, as long as I'm dead but I hope it will not come true too soon )

Coffins, to me, are just a waste of money. People only see it once, then it will be buried. ( Part that is a waste. )
I would however, if needed, the cheapest one possible. ( Be light on the finances of who's paying. )
