She never worries about where she is, or how she will get back home, nor if there will be anything to eat when she gets there. Why should she, when she doesn't realize she's just a dog, anyway? She's happy when she leaves home, and just as happy when she arrives home, again.
Maybe, we could all learn a lesson from Precious: Don't worry, be happy!
Precious is..well, just precious!
She just is.
