If she erected some kind of memorial—I don’t care if it’s a cross or what—on public property, then it should be taken down.
I see these eyesores all over the place and they don’t belong. Putting flowers or a cross or a pagan symbol or whatever on the side of the road ain’t bringing anybody back from the dead. I wonder what the motivation of the people who put such stuff there really is: maybe “look at poor me I’m so mournful?”
