Pillow fight in your underwear. Or play videogames/watch a movie or TV show. I reccommend Firefly.
Im also 14 and for sleep overs I probably play video games, play monopoly, watch horror or comedy movies or tell him things you've heard that might be interesting while in the sleeping bags. Like cheap crazy sale or murder took place.
You know ... watch scary movies , pillow fight , order pizza , play some checkers , and just have fun.
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.
