My Neighbor Leaves a Bowl of Vinegar in the Kitchen Every Night Before Bed. I Thought It Was Strange Until I Learned Why.

When I first noticed it, I honestly thought it was one of those old-fashioned habits people continue doing simply because their parents did it before them.

Every evening, just before heading to bed, my neighbor would place a simple bowl in the middle of her kitchen counter.

The bowl contained nothing but ordinary white vinegar.
