You work for a company and tonight you're supposed to represent it at a conference. After your presentation, the after-party begins. There's a buffet and waiters offering champagne. After chatting a lot with different people to attract potential clients, you decide to isolate yourself on the terrace, New York offering you a view of its illuminated buildings. After a while, a man comes over next to you and lights up a cigarette.

"Your presentation was remarkable." Engage the man in a calm tone.
