Well, it’s official: I am certifiably crazy. During the last seven days I hopped on two 14-hour flights, adjusted to the 13-hour time difference not once, but twice, and now I’m back at work, teaching teenagers. But that’s not all. I did all this traveling for a guy. And not just any guy, but a guy I met on Tinder, in Shanghai, six months ago, who now lives in New York.
