Do you know a what a slumber party is? "slumber" means sleep. It is for kids who stay one night away from their own house and spend the night at a friend's house. They are very popular with kids who are 7, 8 or 9 years old. I don't think Japanese kids do that but I do know that they have a slumber party at the Kindergarten where I teach. I have visited it at night before. I saw the Haunter House. A lot of kids were crying. But, I teach late on Friday nights now so I can't visit at night. But I am invited to attend the breakfast the following (next) morning at 8AM. I always go. The b-fast is usually a rice ball, a piece of bread and a yogurt. (This time I had a yakisoba sandwich.) After eating, I went around to every group of 5 or 6 kids at the table and asked them "What day is today?" in English. We practice this at the lesson. That lesson is always Tuesday. So, it is easy to remember. Did they know that this day was Saturday? There were about 50 kids and only 2 kids knew. That was cool.
