At first glance, Wave All Your Fingers At Your Neighbors Day might appear to be an incitement to approach people that live in your vicinity and, literally, wave your fingers in their faces in an annoying and potentially dangerous manner. Do not be tempted to do this, however, as this is not, apparently, the aim.
It’s more about building bridges than destroying them. Instead of greeting your neighbors with a cursory nod as you usually do, on this particular day you should give them a cheery wave. Not just any old cheery wave though; a wave that involves all your fingers.
Pianists have an unfair advantage because they have undergone special training. Anyone can do it though. So come on, try it now. Pretend you!re playing the piano, but the keyboard is tipped towards you at 90 degrees and is somewhere to the right of your head. Raise your right hand, and play something tinkly. You’ve got it!
