Amen about the coercion part. that was a source early on in my marriage. I personally am more amiable in the morning. Waking up, I feel like I can take on the world! But at night, I just want to rest and not think of any more work, projects, etc. Unfortunately that is when my Darling Wife is alive and ready for anything. We now use this to each others' advantage. If I want to do something that will be a big change I wait until night when my DW is willing to talk and she has to wait until morning to discuss her ideas with me. Not perfect and takes a little more time for us but it works... at least for us.
This actually reminded me of a Sociology class I took where it was explained that male testosterone levels peak in the morning and tend to fall quite a bit by evening. I guess in that way it makes sense that you're so energized in the morning!
I say, do your project anyway!
Maybe get a friend to help if you don't want to do it by yourself? He may come around eventually. Usually when I start a project, the boys start being nosy, and then end up wanting to "help" (aka, show me how to do it).
I talked about wanting chickens for months. Hubby finally says go buy some if it's what u want. We didn't know they had to stay inside until feathered. In the end it wasn't my begging but instead the peeping at 6 wks old that finally got a coop built! Hubby didn't take too kindly to the bright light or peeping while he was watching tv! I loved it. He built the 40 sq ft run. No roost, no nest boxes, no door. Kids and I crawled through 2 ft hole after holding up wire to feed, etc. 2 mths later I built the door and nest boxes and roost. Of course all this time I talked incessantly about everything chickens to the point that he was hurting my feelings by telling me to go talk to my chickens and catch a breath. Now if it has anything to do with my chickens I build it, make it or do it myself. When he tries to figure out what I'm doing or tell me how to do it his way I remind him of what he said to me. His latest quip is telling me to build a coop to put him in so I'll show him attention like my chickens! Lol. BTW- I have since built another coop and started on others. Very empowering and self appreciative for homemaker moms!
