I will warn that, I am not good at telling how much information is enough, so I either go with too much (as an example, during a several-month-late birthday party, it took me several hours to explain the first five days of a three-week holiday I had recently) or not enough (a summary I had to make of a book I had to read in high school (slightly paraphrased to be slightly more correct) was “[Eponymous character] learns that nobody cares about his life in the big city, and that rugby is fun”).
