Sweden
I cut&paste this list from Bianca's BLOG.
I've got in contact with her throght the site Interrail.net where I'm subscibed as cit guide for Milano .
As someone knows I've lived in Sweden for a while (eleven months) and when I've read this I realized I was there for too long 
So, here we go:
You know you’ve been in Sweden too long when
- You think that riding a bicycle in the snow is a perfectly sensible thing to do.
- You regard it as sensible that the ice cream van comes around playing that annoying song when it is -15C.
- The first thing you do upon entering a bank/post office/chemist (anywhere really!) is to look for the queue number machine. You accept that you will have to queue to take a queue number.
- You accept that if someone wants to “follow” you home you don’t need to be afraid. They actually just want to walk you home.
- Hugging is reserved for sexual foreplay
- You've come to expect Sunday morning sidewalk vomit dodging.
- Someone calls you a ”good moron” first thing in the morning and you smile acknowledgement.
- When a stranger asks you a question in the streets, you think it's normal to just keep walking, saying nothing.
- You think that people who wear other colours apart from black, grey, white or blue are exhibitionists.
- You think blodpudding is good
- You think that pay 25 Kr (= 2.5€) for a can of beer at the supermarket is normal.
