So with your guy, if you want to stop nagging, draw him a picture! Make him a list, leave him a note. Yes, of course, ask him as well. Men do have ears, and what you say registers at some level.

No, this isn’t about treating men like children. If anything, it’s the exact opposite. It’s respecting that we are different, that we have different ways of communicating, and making the effort to demonstrate that respect.
