You could put in good a spell for the poor police in this country tonight who have had all their annual leave cancelled to control the yobbish behaviour of louts using halloween as an excuse to break the law. But make it a nice spell.
Yes make it a nice spell that just incapacitates them from the neck down for about 3 hours and makes them see the world from a different point of view, might sort them out for good you never know.
Traditionally, at 12 midnight, you can look in the mirror and see your future beloved. Light one candle (all other lights off) and look into a mirror. You should see the image of your beloved looking over your left shoulder.
btw - I tried this at a girl and it didn't work (surprise,surprise) but you never know! having said that, if I had seen someone looking over my shoulder, I'd have probably cr4pped myself!!
