Tiger's Winter Vacation

Tiger is going to have his vacation starting the day after tomorrow. Again, I have to face the option if I want to hand his vacation to private school system or arrange it by myself. Though I do have a lot of school works as well as academic requirements to meet, I am prone to having his vacation arranged by myself. I want to share with him some of my joy in human knowledge. I also enjoy very much playing GO chess with him despite my constant losing the game.
