When teaching, my old headmistress who is the least woo person in the world said the kid's behaviour deteriates at full moon.
I cannot sleep well during a full moon and i believe it is evolutionary as humans gad to be more alert when predators gad good visibilty...and my goodness, there were some arseholes on the road today!
Plus more babies are born on full moon and my period coincides with it. Aubu?
