In what order do I do these interior painting steps, and why?

My husband and I have a room to paint (starting from drywall) and we argue about it, but neither of us knows the reasoning behind any particular order of steps. Please put them in order for me and explain?

cut in primer
prime trim (window sills etc) – is it the same primer?
roll on primer
cut in paint
roll on paint
paint trim

Primer/sealer does not matter what you do first. You are gonna cover it anyways. Rolling the walls first does let you know how far you could go with the roller however so that you will catch everything with the brush afterwards. You the could do the trim(you could have done the trim first too) However, (if you are doing it all in latex) do the trim in primer, not sealer.
The reverse procedure is done on the wall on the second coat( so that the brush marks are reduced by the roller finish). Do trim last because you hopefully won’t be sloppy about it and spray paint drops around.

    Primer first.If you cut in first,any drips can be rolled out.
    Paint next.Again if you cut in first, you can get away with being a little sloppier.
    Finally the trim.If you want a really good job,take it back down.Paint it then put it back up.Otherwise allow the paint to dry completely before painting the trim.
