living between 3 countries

i'm in krakow right now doing a teaching course, going to luxembourg after, then at some point to toronto for a visit and then back to luxembourg (where i need to work of course to get the money for that travel!). i was just thinking today how i really like living between these 3 countries - it's quite interesting, i do different things in each and enjoy/dislike different aspects about each (unfortunately, luxembourg has the honour of getting the most dislike - its size will always keep it lower on my list). my wallet is stuffed full with different bank and id cards!
