Random Interesting Facts that I learned in Japanese preschool:
1) Stoplights are actually Red, Yellow and Blue (I swear they look green).
2) Snowmen are made of only two big snow mounds NEVER three...(I was teaching Christmas words and we had a long discussion about the Japanese requirements in order to be considered a snowman).
3) Every child knows the word Christmas wreath (I just call it a wreath), but not candy cane.
4) Children must raise their hands as if answering a question when walking across the street. When I was driving the other day, I saw one girl doing that, and I just thought she was playing or something. The point is, I saw her and paid attention.
5) Children who can barely walk can be trained to take their lunch trays/bowls/cups, etc to the kitchen on their own without someone helping them along. They looked like little toddling zombies that would stumble in one direction, remember what they were supposed to be doing, stumble in another direction and finally make it to the kitchen WITHOUT prompting. This blew my mind.
