That means if you are a kid then you need to tell your parents about your problem. And maybe they will fix your problem or maybe not. But if you are a aldult then tell the house owner what you do not like about the house. Or whats wrong about it. And that's what you should do if your room has no room.
Tell your parents to make him stay out or ask your parents if you can get a lock for the outside of your room. If he's your little brother, all it will take is a scary story though.
Oh Boy!! No matter what, I belive my parents deserve to know the truth. No matter how much they may be upset its better than lying to them for eternity. You should tell them, but when you feel your ready to. And that doesn't mean next year! :)
Tell one first, alone in your room. He/she can then tell the other parent. Just say "I'm pregnant".
