So how did a heavy table and umbrella stand move by itself? It was one of those summer thunderstorms, but there was no damage to the umbrella, which was open during the rain. There were no obvious signs of severe wind such as downed branches or leaves. There was no sign of a struggle. The Husband heard nothing except the thunder and insists he did not move it. The squirrels claim they saw nothing, but their credibility is questionable. The birds ain't talking.
I look forward to your responses to solve the mystery!
