Quote from Moira in Smoke Signals
Moira: We seem to have found ourselves alone again, Mr. Rose. Johnny: Moira, that was 15 years ago! Moira: Mm-hm? Johnny: What if someone sees us? Moira: Who knows what will befall us tomorrow, John? You could be hit by a Mack truck, or bopped on the head by a tiny piece of space debris!
