Oh my gosh, I love Shoelace's expressions here! Well, they need something to cheer them up when things are especially bad. Besides, there's this line from the book 'The Tale of Despereaux' that fits. A person "might as well be happy, since it doesn't make a difference to anyone but you if you are or not." A bit cynical on the speaker's part, perhaps, but there's some truth to it.
