     I'm glad that my parents are going to decorate
; my bedroom. I really want my walls to be
; painted blue with curtains of the same colour,
; because blue can make me feel calm and
; peaceful. The colour of the floor can't be too
; dark, because light colours make the floor
; look clean even if there is dust on it. There
; shouldn't be too much furniture so that the
; room looks larger. I'm sure I'll feel relaxed
; and happy in such a room, especially when
; I'm feeling stressed.
