Vacation

I was watching a video on YouTube, posted by geriatric1927, and he was discussing the drudgery of home and the anticipation of leaving that for vacation. It occured to me - maybe we go on vacation so that we will appreciate home a little more. We enjoy our vacation, usually, but don't we then enjoy and appreciate coming home again? Maybe vacation has a dual purpose: one, to let us get away and "relax;" and two, to let us appreciate our home.
