How we cite our quotes:
GARCIN: So it comes to this; one doesn't need rest. Why bother about sleep if one isn't sleepy? That stands to reason, doesn't it? Wait a minute, there's a snag somewhere; something disagreeable. Why, now, should it be disagreeable? ...Ah, I see; it's life without a break. (27)
More importantly, it’s life without solitude. Never sleeping means one is never alone…
GARCIN: You see, I'm fond of teasing, it's a second nature with me – and I'm used to teasing myself. Plaguing myself, if you prefer; I don't tease nicely. But I can't go on doing that without a break. (31)
This line is strikingly similar to Inez’s later claim that she is "like a live coal" kept alive "in other people’s hearts." Garcin, too, needs to torment other people to survive.
[Valet goes out.] [Garcin refrains from looking at Inez.] (64)
This is one example of Garcin’s accommodating nature, though he doesn’t yet realize the value of keeping his head down. By not looking at Inez, he’s trying to avoid reducing her to a mere object.
