I don't know that she knows that she's missing anything. Nobody in her part of the world is in a position to be able to take a vacation. The closest anybody comes to that is Herbert "Daring" Dashwood, the Wasteland adventurer whose life story Three Dog broadcasts as a radio program- and for him it's not a vacation, it's retirement. He's done his work and he's got his resources and he's found a safe place to live, so that's that. Other people do their daily work because that's what you do. It's different out in the Mojave- the New California Repulic's civilized enough that people actually willingly travel from home to New Vegas to stay in the casinos and spend money and see the Strip- but the Capital Wasteland, not so much.
