For people who live alone and eat one meal a day!
I would buy this, but then I’d have company over one day in August, and they’d have gum or something, and ask me where the napkins are, and I’d start to point them to the non-calendar napkins, but they’d just grab the calendar ones without even listening, and then proceed to obliterate tomorrow’s napkin, thus ruining a whopping 237 days (give or take) of carefully orchestrated mouth-wiping, and I’d just sit there devestated and silent, and they wouldn’t understand me at all.
