How should I answer

[Cadet]

Yes but her question will be why didn't I tell her what I was doing.

Seems to be one-way streak of how we are suppose to communicate.

I think the answer is in your first post.

You are Mr MOM.
Did that change since the other day?

I think you are also MR DAD.

I also think the best idea here is to say as little as possible.
To speak with actions and not words.

You have been fired as a husband but do not give up being a parent.
