Viewings really are sort of macabre, but the reason people do it is to get a last look at the person you remember, so to me it makes sense to put the glasses on if that's the way the person was most often seen. I guess by the same token, if you always dressed like a Deadhead, rather than clean you up in a suit and tie, they should probably lay you out unshaven and unbathed in your tie-dyed tee and bandanna. I want to be harvested for any usable organs, then vaporized without fanfare. I also don't see the point in keeping my ashes in a vase -- I'll just let my S.O. scatter them wherever she thinks is appropriate.
