i've often wondered if these post holiday blues have something to do with life just going back to normal and going back to how it was

example: someone who lives alone might look forward to the holidays because they get to eat a meal that they wouldn't usually have at the other time of the year, see people they wouldn't usually see, do things they wouldn't usually do, etc etc, and yeah, their expectations might be high

at the end of it though (in all cases I can think of just one day), all the decorations go back, the food goes away, everyone goes home and you're left thinking... well, that was cool, I enjoyed it- but my life hasn't changed in the slightest- tomorrow I'm going to wake up and things are going to be totally normal
