When Marissa spends the night, we go to bed with some sliced apples and a movie. The apples have become a habit. She used to tell me she was hungry and wanted candy. I convinced her that she would rather have an apple. : )
Next time she spends the night, I will rent shrek 1. She will love telling me all about it but if it is like when she reads me a story, she won't follow the author's script!
That's why I suggested indulging her!
There's a lot of body reference humor, as you'd expect from folks who think they are writing for kids, but it is moderately innocent. There's a touch of adult humor as well, particularly in reference to other movies and such. They increased that tendency in the second movie.
Maybe you'll be able to take Marissa to see the second movie, (that will give you an excuse!!)
Sounds like a fine party for you two.
