Equally, since it's totally friday in some parts of the world....I'm going to go ahead and start the love potion plot.
Dumbledore, though mysterious means, (not really), managed to get treats for the whole school. This being two kinds of flavored cookies and a whole lot of crisps. If you liked something as a teen, you were stuck in school and Dumbledore called off classes for Friday, for an early weekend kind of thing, you would so stuff your face. Don't even lie.
So now you have two options.
If you eat a pink marshmallow cookie first: you will find ONE person you absolutely love and that will be your object of desire for 72 hours. READ EM. SEVENTY-TWO.
If you eat a green caramel cookie first: you will be terribly conflicted and possibly love two people at the same time or three. Possibly four. Maybe the entire castle.
What Dumbledore didn't realize, and couldn't have known, was that a disgruntled employee that made the cookies (because they're usually supposed to just make you want to dance and enjoy yourself) went ahead and dumped a whole bunch of love potion into the cookie mixes. Because he wanted to see what would happen when they went out and people did stupid things. He wanted to get the employer sued or mauled by kelpies--something. So now you get to deal with the consequences over a bad day at work.
Please enjoy.
