Routine
After the workweek, coming into the weekend might mean partying, clubbing, or hanging out with friends. But in married life, it can often mean what this dude tweeted. While a couple might always want to think of something to do, odds are laziness and indecisiveness will get in the way.
This is an all too common scene for the married couple. Sitting on the couch and pondering things to do will inevitably end up with one or both of the couple getting too tired to do anything at all. Nights often end with cuddling up on the couch and falling asleep.
