To my sister: Alright, fine I get it. I know you love your boyfriend but bringing him over after our parents explicitly stated 'Do not bring him over again' is against our household rules and this is the second time you have broken that rule. Again, they are out of town and again you decide that bringing him over is a fun way to pass the weekend. I do
not appreciate picking up your spilled beer bottles, your mess in the kitchen, cleaning the unflushed plugged and BROKEN toilet, closing all the window so the neighbors can't hear you roughousing in the living room, and making sure that the cats stay fed and SAFE while you decide to set a drunken example in this house.
I will not ever again keep this a secret from our parents, and if this behavior persists, the police will be called. You are 18 and you do not live in this house. And while you are in this house, you are expected to follow the rules of this house. You want to be in charge, I understand. But there comes a time where you must abide by the rules set by the people who own this house, and so far you've done such a bang-up job.
You think you are mature enough to make your own decisions but you can't even take five minutes out of your spoiled life to see that you are causing an inconvenience to the rest of the family whilst the parents are out of town. But here's the thing sweetheart. You are not in charge of this house, and you do not set the rules. It's amazing you're still alive with the stupid things you've done. Being 18 does not make the world suddenly revolve around you. Grow up and act like an adult.
I feel better.
