Until it dawned on me. The weather.
Saturday and Sunday were so gorgeous out here that I wore a sundress both days and we kept the windows to the apartment open for hours and hours.
The weather. That must be it. Everyone's suddenly starting to feel like they need their beach bodies back! I don't know if it's subconscious or not, but I think it's really interesting that even in this day and age, even in this ultra-modern and ultra-urban lifestyle of New York City, humans' actions are still so dictated by nature.
