I personally see We Speak as a projection of one's own world onto another. You may feel that there is 'work to be done' in the yard, yet your H may look out and see a yard that looks fine just the way it is. When you say, 'we have work to do,' you are assuming he shares your views, goals and objectives on the state of the yard.
Now, if you look out into the yard and see the weeds that need pulled and grass that needs mowed, you may say to your H... "Honey, the yard, to me, looks like it could use some work. If you don't have other plans this weekend, would you be willing to help me out with it?"
I guess, to me, the second approach is much more likely to illicit a positive response than the former. Goes back to Burg's post on 'otherness.' The latter recognizes 'Otherness' for yourself and your spouse, in the former, or We Speak, there is no sense of 'Otherness.'
