i carry your heart with me it's not about being impressed; it's about being captivated...

Do everyone else a favor: when you are in another country, it is your responsibility to communicate in their language.  Do NOT expect them to know your language and do NOT get mad and yell at them when they don´t.  Realize that you are not in your home - you are a guest in someone else´s land.  Realize that you are not always right nor are you automatically a victim, and even if you may be right in your country you need to take into account the fact that you are in a different country.  Respect their ways, their customs, and their rules.  When you get mad and yell, not only do you look stupid but you also reflect on the rest of us who are here to experience another culture.  Your outbursts give a poor impression of your home country, as well as making the evening much less enjoyable for your travelmates (although, after we took her home, we did get lots of free drinks from the waiter who she yelled at).
