We do the last of the planned and unplanned activities. We pack bags and look around to make sure we've forgotten nothing. We look behind at what we've done, and ahead at what we still have to do. Vacation is almost over.
The glory of vacation is that, if it's done well, you really can have a break from the routine or the difficulty or the stress of your day to day life. The problem with vacation is that, if it's done well, you have a hard time re-entering the routine or the difficulty or the stress of your day to day life.
So, as we pack, and finish, and look around, we relive a bit of the glory, and we manage a bit of the problem. There wouldn't really be vacation if there weren't the day to day life to take vacation from. And presumably, if there continues to be day to day life, there will be vacation again.
We do the last of the planned and the unplanned activities. We pack and look around, and we prepare to exit vacation and re-enter our day to day. It's not easy. But I guess that's why they call vacation vacation...
