Attempted arson!
If you found a piece of charred paper on your car, you’d probably think that someone was out to get you. At least, that’s what the OP thought when they first posted this image on Reddit. However, it turned out that this leaf wrapped in a charred piece of paper was less threatening than it looks.
In fact, this was done by a Wiccan, a follower of a pagan religion that burns pine trees to ward off evil spirits. The commenter assured the OP that whoever did this was looking out for them. It’s pretty neat to have a kind witch looking after you, but maybe they could leave some gas money next time.
