Your standard man, at this point in the Christmas season, has purchased zero gifts. He has not yet gotten around to purchasing an acceptable gift for his wife for last Christmas. He did give her something last year, but he could tell by her reaction to it that she had not been dreaming of getting an auto emergency kit, even though it was the deluxe model with booster cables and an air compressor. Clearly this gift violated an important rule, but the man had no idea what this rule was, and his wife was too upset to tell him.
