A Full Moon Does Not Change Behavior
You have head it a million times....."Ohhhh, must be a full moon tonight!"
Last night there was what they call a "Harvest Moon", or a full moon, and everyone was tweeting about how the crazies were in full force, but in reality, there is no connection between a full moon and people acting crazy.
If you run into crazy behavior, its probably because it is their normal behavior but unfortunately you had to witness it.
