do you have personal experience examples ......

Your description of "奧地利人很有禮貌，談吐友善得體，不像法國人那麽傲慢，也不像意大利人那麽喋喋不休；不像西班牙人和拉美人熱情似火，也不像美國人大大咧咧像個孩子" impacts reader like me because I am deeply wondering whether you copied such ideas from books (novels) or generated from your personal social experience with local people? Any examples?
