Reverse culture shock?

I've heard from several people that sometimes returning home after an extended period away can be more difficult than making the initial adjustment to a foreign culture. I can sort of see that, after all, adjusting to a foreign culture is one thing, but returning 'home' to find that you feel alien in familiar surrounds could be really disconcerting.

I'm sure we'll feel a little weird when we get home, and certain things will be hard to readjust to. It's hard to predict what sort of form this might take, but I'm willing to bet that nonsense like this may figure prominently.

Welcome back to a different kind of crazy...
