im 14 and going into high school. i have a house thats entirely remodelled. i have two other bros. one 13 and one 6. and i had to share a room with both since i was born until now. i have my own new room which they have already painted lavender. i hate the color. i wanted hot pink with black ceiling.
but i have to work with what i have. what are good themes, furniture, and objects to have in my room
