About a year ago my wife had a coworker whose child drowned at the lake. They were having a wake at the funeral home and she decided to go with a pile of watchtowers about death of a loved one.
I had tell her it would be incredibly rude and if they want to believe there child is in heaven with Jesus right now, just let them. Of course the whole thing turned into a huge fight.
Once we got to the funeral home and saw the grieving family, she quietly gave up on the idea and just gave her condolences.
