So. On. Point!!
I had this in my relationship.
I asked my husband SO MANY TIMES when he took a shirt off the hanger, to please put the hanger in the middle of the rack.
This saves me the task of hunting down the empty hangers from in between all his shirts. Very similar to your socks situation.
I thought he was just ignoring me too. And I felt the despair. Then one day I came in and found him putting his hangers into the center for me. I actually had tears come to my eyes.
He doesn’t do it all the time. But it’s a huge thing that he’s starting to get it.
Your article is awesome.
