One of the great parts of our old apartment was that it had 2 fairly large closets for clothes, situated right next to each other in the hallway. Both were about the same size so we had a his and hers — done and done!
The great part about not having to share a closet is that it's okay if his closet gets messy, because that's his own business. And similarly, if one day I want to take everything out of my closet and re-organize it (because that's how my mind works), I don't have to make that an activity that takes up his whole Sunday afternoon, as well.
Now, in our new house, I'm finding the closet situation isn't quite so great. Well, I should clarify, the master bedroom has the worst closet of all three bedrooms. In short, it's just not big enough for the 2 of us. I could probably write at length about its other short-comings, but I'll save that for the day when we finally replace it, but for now we have to live with it — until I can execute on my dream closet.
