So tell her your intentions. Tell her you both want to get a bigger house or want to travel some or maybe that you want a promotion or something. Give her a significant reason and then be done with it.
It could even just be "Because we aren't ready". But you need to give her a firm reason. Then tell her you'll do it when you're ready and leave it at that.
Change the subject as needed.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
