““You take your flashlight out on your walks, right?” Simon asked. “Depends on the moonlight.” “From now on, take it with you every night. When you’re out walking this way, you’ll pass the gazebo, where, chances are, I will be smoking.” “Then what?” “You can signal—say, three times if you want to take a walk with me. Twice if you want to walk alone. that way I’ll just let you walk on. It’ll be like a military code. No one gets hurt.” I laughed. “that’s silly and charming.” “I try. I can signal back with my cigarette lighter too,” Simon said, holding up the lighter and firing off three short bursts of flame. “So, like, if I see you first and I happen to not wish to talk to you, I can fire off two bursts and block you in your tracks.””
