1. Getting to the restaurant/movies/concert before the rest of your friends.
2. Deciding whether you're shaking hands or hugging (or both??).
3. Making small talk with hairstylists.
4. Having absolutely no idea if someone's flirting with you or just being friendly.
5. Elevator rides.
6. The never-ending loop of asking each other "how are you" when greeting someone.
7. Responding to a compliment.
Actually zero things you can think of to say without sounding like an idiot.
