Following up in the SC tradition of comments on holidays, particularly Mother's Day, an observation about fatherhood and possible worlds.
As with Mother's Day, SC went shopping for cards, and was reminded of how incredibly fine-grained the categorizations of mothers could be. This time around, though, he noticed one category in particular that led to some additional thinking: "father-to-be".
Ostensibly, such a category is intended to apply to men who know that their wives/girlfriends/one-night-stands-with-good-legal-counsel are pregnant and expecting delivery in the foreseeable future. Another possible use -- one which SC is very leery of -- would be to inform said men that their wives/etc. are now pregnant and expecting. But an optimistic Hallmark product planner might go further than that, and hope that it would also appeal to those women who believe that their men will be fathers at some time in the future. Going even further, they might introduce a new category: "father-in-potential", which could be justifiably sent to any man who, in some possible world not necessarily their own, could be a father. This would expand the universe of possible card recipients to be nearly all men (minus a few very unfortunate types), and because of the additional revenue potential, SC is frankly shocked that Hallmark hasn't beaten him to this one.
Of course, there's one scenario in which your host can even imagine for sending Father's Day cards to women. In the event of a single mother taking on the roles of both mother and father, perhaps the really aggressive Hallmark card writer could imagine a card saying "Thanks for all you do, on both Parents Days", maybe with an appropriately feminine color scheme. And then they could get around to doing the same thing the next year for single fathers; SC suggests they might want to try introducing some Mother's Day cards featuring power tools, and see if it works.
On an unrelated note, those of you looking for "Huntington contra Nunberg" will have to wait until tomorrow, while SC takes the rest of his Father-in-Potential Day off.
