Summer vacation has started Long summer vacaton has started. My son's school was done, and so my class in collage. I can't beleive why it is so long in US. How working parents manage this? Summer camp is not cheap, and child care center neither. In US, it is not allowed to let kids alone at home when they sre under 13years old. In Japan, there are no paticular rule like that, so they stay alone and hang out with friends keeping house key with them when they are around 10years old; it depends on their house rules. That's why both parents can work during summer vacation in Japan even if thery don't ask someone to watch their kids. I am just wondering how parents can handle this long vacation in other countries.
