"No thank you, I—I really am not thirsty, and I must go."
"I don't see how you are going to get away now, the town guard knows you are here and is bound to arrest you if your eyes are not crossed."
"What have I done?" asked Billy.
"Nothing, only it's not bad luck to meet a straight-eyed person, and if you can't bring somebody bad luck you're not allowed in the city."
"But how do they know I am here?"
"Their noses are itching because a stranger has come to call. Their noses are very sensitive to strangers. It makes them such careful guards."
"Have they guns?" asked Billy.
"Oh! yes, they all have guns that are not loaded."
"Oh! well, then, they can't shoot me."
"I guess you don't know much about guns—because it is always guns that are not loaded that shoot people."
