I woke up four in the morning and cut some discs out of a cardboard for my son's handicraft. Japanese elementary schools give children a bunch of homework during the summer vacation and one of the formidable task is the handicraft and/or study. My son is tackling with a mechanism of gear wheels, so I'm also dedicating some of my time to the aid of it. I think he's really good at exploring some new idea and knowledge, but is a little bit easy to drift his mind when things don't go well. I want him to acquire persistence which I think I couldn't learnt well.
