I plan on going a trip to Europe and Asia in a few months.  I might stay one month in Europe and another month in Asia.  What other language would be good for me to learn of I plan on going there by myself as a tourist.  Im thinking about joining a tour group but i would like to tour the places by myself.  Should I learn the basic greetings per country or is there one langauge that would help me communicate with the other people?  I currently know English and Spanish, but other than that you can ask me if I'm ugly in a another language and I would answer "Hell Yeah"
