It’s like that old shampoo commercial: I throw together a cocktail party. A guest snaps a picture and posts it, where it’s seen by two friends who show it to two friends and so on and so on. Before I’ve popped the first cork, I’ve pissed off several people who weren’t invited but still receive Facebook notifications from our circle of friends. I admit, I too feel a twinge of FOMO when a group selfie (minus me) drifts into my Instagram feed. Perhaps we should start enforcing a strict #latergram policy or create a complicated, explanatory hashtag. Or maybe I’ll just confiscate all phones at the door like Kimye did on their wedding day. The truth is, I know I’ve succeeded as a host when everyone is having such a good time, they forget to take photos at all.
