Wave All Your Fingers at Your Neighbors Day
The creators of Wave All Your Fingers at Your Neighbors Day only had this to say about it: "After all the challenges we and our neighbors have faced, it’s time to put it all aside for at least one day. Wave 'hello' to everybody, and mean it." The day's name gives the impression that perhaps sometimes people wave at their neighbors by only using some of their fingers. Being that the day is also about a "time to put it all aside," it seems to suggest them sometimes people "wave" at their neighbors when they aren't getting along with them. This is likely implying that sometimes neighbors give each other the finger. On today's holiday, they shouldn't do that, but should instead give a normal wave.
How to Observe
Celebrate the day by waving and saying hello to all your neighbors. It is especially important to wave to those you dislike or don't get along with. This is not some empty-gestured holiday, however. Waves to your neighbors should be sincere. Perhaps this will help you forge a new friendship or at least a truce, with those neighbors whom you do not see eye to eye with and have only been waving at with a few fingers.
