If I've learned anything during my extensive 23 years on this earth, it's not to mess with the all-powerful being that is the moon. Ocean tides? Moon. Menstrual cycle? Moon. Weird-as-heck ish happening with dogs? Moon. Your boyfriend forgetting your birthday because he was 'out with his boys'? That's not the moon—that's just him.
My main point here is that you can tell a lot about people's energies and moods when you start paying attention to moon cycles. Different points in the lunar cycle mean different things, and each month, the full moon is said to affect a different thing, and ends up being named as such.
