You needed to draw up a contract detailing your responsibilities, pay per hour and what you WONT do. You screwed up by not having a contract. And you voluntarily agreed to do housecleaning and now you want to back out.
You need to approach her with a contract and if she doesn't agree, you will lose this client.
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.
