I have absolutely no idea Where that large stain on my ceiling came from But it's getting larger every day. It used to be only really the size of a quarter (I measured) But now it's the size of my palm. I've asked my parents, But they say its probably just from moisture. It hasn't rained. They say they'll get it fixed, but A stain the size of my hand Right over my bed, Getting bigger every day, Is a little disconcerting.
