Millie: How should we choose the colours for the rooms of a house? Sandy: Most people think light colours are better than dark ones. Millie: Yes. I notice light colours make rooms seem larger. Sandy: Sure. I also know blue can make us feel relaxed. Millie: Yes. My mum says blue is suitable for bedrooms. I also find some people prefer orange for their dining rooms. Sandy: True, but it depends on personal taste. Anyway, we should choose the colour which makes us feel comfortable. ∧ (that) ∧ (that) ∧ (that) ∧ (that) ∧ (that) ∧ (that) ∧ (that) Sandy is chatting online with Millie about room colours.
