There are so many threats out there right now, but husband alerted me to an important family historical threat that dates back to Halloween, 1975. This gem is from his father's journal:
October 31, 1975
We had, I think, only two groups of youngsters come by, trick or treating, but three groups who were on a scavenger hunt. I couldn’t help, but Arlene did give some purple threat to one group.
Note: Arlene was his wife. I can imagine her issuing that purple threat in her best, most eloquent prose.
