Partying in Eindhoven as in: in general, or as part of the introductory week?

First thing: yes. Second thing: no. I don't have any friends going to Nijmegen (sadly enough). They all stay in Eindhoven (we have a large university too), or go to Delft or Maastricht. I will stay in contact with them too. Sometimes you hear how friendships are lost because people move to another city or country, but we have said to each other that that's not going to happen with us.
The study will take four years (I'm everything goes as it should go). I don't have picked any option-subjects yet, I think it will be something in the direction of subjects related to Political Science or History.
