Oh well........I sort of had to. Most of the time I spend in Europe is for work, first I worked as a contractor with DCATS and they have a joint project with MOD in England, plus I need to stay in UK for one year to register my British Citizenship, Then I sort of contracted to EU Military Command and conduct some study on interoperability between NATO and EU command. Then I was staying in Brussel for 6 months, and finally bring me to Sainte-Menehould for another 8 months.
Then I married to a Swede and I stayed in Malmo for 2 whole years with her and now I moved to Australia......
I guess workmate is a bit colder than classmate, I mean back when I was an undergrad, I hang out with my dorm-mate and classmate all the time, but then you got work, people from work usually, well, just work, and most of them have family and stuff to take care of, you don't hang out with your workmate that much. Then it gone worse after you got married, That's the end of your social life.....
