It's true that nagging is a two way thing, that's to say that both gender nags. Like you've mentioned, men nags more these days, I have three siblings in my school who complained to me about their father nagging that's why they stay back at school to make sure they won't meet him at home. The smallest one said when he comes back from work they will all sleep compulsorily. I can understand, things are becoming tough now for them.
I'm sorry is truly a remedy to calm the other party down.

Best wishes to you my friend.
