For my part, I mostly made one of those unconscious choices a long time ago, that if this sort of thing happened, I would usually choose to leave Azeroth and go experience real life. I had realized that it's too easy to lose oneself in the imaginary world and then come back to real life with a sense of emptiness. But with the right kind of moderation, I feel like both my time on Earth and my time in Azeroth are full and enjoyable.
What do you do when someone says "do you want to go hang out with us?" when you had planned to play WoW? Do you usually choose one or the other, or does it totally depend on the situation?
