Rose,
Those things you want to change about him are the things you should let go of. Stop nagging him about it. Leave it there or put it away but don't say a word anymore.
The first thing I started with was not telling Ward what to wear....and it was hard when faced with his choices!! Ward cooks a meal...but does he clean up?? Nope! He will wash a load of his cloths (he is not allowed to touch mine) but will he take them out of the dryer? Nope! I fold them and put them away.
How important is it??
Oh and a little rebellion would be to HIDE that mower!
Anything else you want to change about "HIM"?? (wink wink)
Hugs,
JT
