Sadly, this was indeed based on real life. The kids had finished putting all of the ornaments on and 45 minutes later it all came crashing down. As the strip implies, re-decorating the tree was faster the second time around.
From 2009. Those who elaborately decorate their houses for the Christmas season, which in my mind does NOT start until after Thanksgiving, know exactly where this one is coming from. As you spend hours setting it all up that little voice is saying “Why? Why are you doing this when it’s all coming back down after four weeks?!?” But it looks awesome so you still do it.
