Marge, do you and dick use a sprayer to paint inside? My brother in law, who paints for us, used it in many rooms, it did a nice job, and much faster, except for the extra preparation time, like removing a/c grilles, switch plates, etc, and covering ceiling fans. we decided to use a semigloss paint for walls, ceilings and trim, instead of flat on walls and gloss on trim, to avoid masking all the trim, or the walls.
