How to talk when the music's blaring
“Typically, people stand two or three feet apart, but you should try to cut that space in half. If you’re talking to someone of the opposite sex that you’ve just met, you don’t want to be face-to-face. Move a bit to the side, turn your head so you’re almost talking into the person’s ear. Keep your sentences short and
speak clearly: Also, be aware of your breath.” –Don Gabor, author of How to Start a Conversation and Make Friends
