According to Tom Sawyer it is bad luck. If I remember correctly his “adventures” began when a spider dropped into the flame of Tom’s bedside candle. And we all know how his summer turned out. But that novel was full of old superstitions that we’ve forgotten.
I haven’t read Tom Sawyer since the fourth grade.
Thank you for refreshing my memory about the spider’s being
associated with bad luck in the book and in superstitious lore.
I am not superstitious, but I am careful... ;-)
