One thing that struck my wife and I here is how far we are from this being a vacation. We can go to Venice for the day, but we grocery shop on our way back and only go there when we have something to do.
Our separation from home and our lives is evident every 5 minutes. Finding what we need is difficult, talking to people to find those things is more difficult. We bike and walk to many places because that is how you do it. I work 10-11 hours a day and am quite tired after.
This is not a complaint: it's a blessing. It's a blessing to really live in a place so foreign, not just visit and see the shiny parts, but to be a part of the grimy parts. We struggle to even get through some days (spending 6 hours trying to navigate getting a cellphone fixed, walking a kilometer only to find out a place is on it's 3-hour siesta, etc.) and smile through others, but we live them all. My employer was (ehem) tardy in sending us. My wife quit her well paying job almost a year before we left because we "were leaving later that month". The leave date has been pushed back 10 times or so, but always so soon that we didn't have time to re-settle our lives. To say we have had a stressful (and frugal) year is an understatement. But we will remember this year until we die.
