This is all about property rights.
She doesn’t own her residence. The city she lives in does. THEY get to make the call on who occupies it. The only claim on the property is that which she is permitted by the city. No more, no less.
I had a quick email exchange with a Swedish friend yesterday. I should just copy and paste it but the jist of it was, "Everything is going great. I start my new job on October 17th (you give 3 months notice there so you can dick around for months on end). Spain was wonderful, spent four weeks on Costa del Azahar"
What, me worry?
