Different families will have different expectations. On my first time sitting I ask the parents if there is something specific that they don't want me to do. I have one family that they are totaly fine with it if I take the kids to the kids karate class I teach at for a free lesson.
Another family I babysit was horrified at the idea when I sugested it. So just ask if you don't know?
Bring other people to the house or smoke or drink or spank them. Or take them out of the house ( but my sitter only comes like at nights when my husband and I go see a movie etc. Like twice a year lol during the day of course they could go to a park etc ).
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.
